Taking advantage of the extreme absolute accuracy, sensitivity, and resolution of noise-immune-cavity-enhanced optical-heterodyne-molecular spectroscopy (NICE-OHMS), a variant of frequency-comb-assisted Lamb-dip saturation-spectroscopy techniques, the rotational quantum-level structure of both nuclear-spin isomers of H218O is established with an average accuracy of 2.5 kHz. Altogether, 195 carefully selected rovibrational transitions are probed. The ultrahigh sensitivity of NICE-OHMS permits the observation of lines with room-temperature absorption intensities as low as 10−27 cm molecule−1, while the superb resolution enables the detection of a doublet with a separation of only 286(17) kHz. While the NICE-OHMS experiments are performed in the near-infrared window of 7000–7350 cm−1, the lines observed allow the determination of all the pure rotational energies of H218O corresponding to J values up to 8, where J is the total rotational quantum number. Both network and quantum theory have been employed to facilitate the measurement campaign and the full exploitation of the lines resolved. For example, to minimize the experimental effort, the transitions targeted for observation were selected via the spectroscopic-network-assisted precision spectroscopy (SNAPS) scheme built upon the extended Ritz principle, the theory of spectroscopic networks, and an underlying dataset of quantum chemical origin. To ensure the overall connection of the ultraprecise rovibrational lines for both nuclear-spin isomers of H218O, the NICE-OHMS transitions are augmented with six accurate microwave lines taken from the literature. To produce absolute ortho-H218O energies, the lowest ortho energy is determined to be 23.754 904 61(19) cm−1. A reference, benchmark-quality line list of 1546 transitions, deduced from the ultrahigh-accuracy energy values determined in this study, provides calibration standards for future high-resolution spectroscopic experiments between 0–1250 and 5900–8380 cm−1.

A fundamental equation of state was developed for propylene glycol. It is written in terms of the Helmholtz energy with the independent variables temperature and density. Due to its fundamental nature, it can be used to calculate all thermodynamic state properties from the Helmholtz energy and its derivatives with respect to the independent variables. Special attention was paid not only to accurately reproduce the available experimental data but also to correct extrapolation. Therefore, this equation can be used for application in mixture models. For the development of the present equation of state, the available literature data were supplemented with new experimental speed-of-sound measurements, which were conducted in the temperature range from 293.2 K to 353.2 K with pressures up to 20 MPa. High accuracy was achieved by applying the well-established double-path-length pulse-echo technique and a careful sample preparation.

In previous papers, specific correlations were proposed to reproduce the surface tension values selected for several families of fluids and for wide ranges of temperatures. In this paper, the surface tension of n-alkanes is considered. For that, the data available in DIPPR and DETHERM databases and in Wohlfarth and Wohlfarth [“Surface tension of pure liquids and binary liquid mixtures,” in Landolt-Bornstein, New Series Group IV Physical Chemistry Vol. 16, edited by M. D. Lechner (Springer-Verlag, Berlin, 1997)] and its updated supplements (2008 and 2016) have been compiled. In most cases, a significant number of new data have been added, which were published elsewhere during the last few years and that were not included in the previously mentioned sources. All the data and values available for each fluid have been carefully screened and subsequently fitted to the Guggenheim–Katayama model, which includes two to six adjustable coefficients for each fluid. As a result, recommended correlations for 33 n-alkanes are proposed, providing absolute deviations below 1.65 mN/m and mean absolute percentage deviations below 2.1%.
在以前的论文中，提出了特定的相关性来重现为几个流体家族和宽温度范围选择的表面张力值。本文考虑了正构烷烃的表面张力。为此，DIPPR和DETHERM数据库以及Wohlfarth和Wohlfarth[“纯液体和二元液体混合物的表面张力”，Landolt Bornstein，New Series Group IV Physical Chemistry Vol.16，由M.D.Lechner编辑（Springer Verlag，Berlin，1997）]及其更新的补充资料（2008年和2016年）中的可用数据已经汇编完毕。在大多数情况下，增加了大量新数据，这些数据在过去几年中在其他地方发布，但没有包括在前面提到的来源中。每种流体的所有可用数据和值都经过了仔细筛选，随后拟合到古根海姆-片山模型中，该模型包括每种流体两到六个可调节系数。因此，提出了33种正构烷烃的推荐相关性，其绝对偏差低于1.65 mN/m，平均绝对百分比偏差低于2.1%。

Results from the application of our optical potential and relativistic optical potential models to positron scattering from gas-phase zinc (Zn) and cadmium (Cd) are presented. In particular, integral cross sections (ICSs) for elastic scattering, positronium formation, summed discrete electronic-state excitation, and ionization scattering processes are reported for both species and over an extended incident positron energy range. From those ICSs, the total cross section is subsequently constructed by taking their sum. We note that there are currently no experimental data available for any of these scattering processes for either species, with earlier computational results being limited to the elastic channel and restricted to relatively narrow incident positron energy regimes. Nonetheless, we construct recommended positron cross section datasets for both zinc and cadmium over the incident positron energy range of 0–10 000 eV. The recommended positron cross section data are subsequently employed in a multi-term Boltzmann equation analysis to simulate the transport of positrons, under the influence of an applied (external) electric field, through the background Zn and Cd gases. Qualitatively similar behavior in the calculated transport coefficients was observed between both species. Finally, for the case of zinc, the present positron transport coefficients are compared against corresponding results from electron transport with some significant differences now being observed.

In this work, we compiled and critically evaluated rate constants from the literature for abstraction of H from the homologous series consisting of the fluoromethanes (CH3F, CH2F2, and CHF3) and methane (CH4) by the radicals H atom, O atom, OH, and F atom. These reactions have the form RH + X → R + HX. Rate expressions for these reactions are provided over a wide range of temperatures (300–1800 K). Expanded uncertainty factors f (2σ) are provided at both low and high temperatures. We attempted to provide rate constants that were self-consistent within the series—evaluating the system, not just individual reactions. For many of the reactions, the rate constants in the literature are available only over a limited temperature range (or there are no reliable measurements). In these cases, we predicted the rate constants in a self-consistent manner employing relative rates for other reactions in the homologous series using empirical structure–activity relationships, used empirical correlations between rate constants at room temperature and activation energies at high temperatures, and used relative rates derived from ab initio quantum chemical calculations to assist in rate constant predictions.

New equations of state for the binary mixtures H2 + CH4, H2 + N2, H2 + CO2, and H2 + CO are presented. The results are part of an ongoing research project aiming at an improvement of the GERG-2008 model for the description of hydrogen-rich multicomponent mixtures. The equations are formulated in terms of the reduced Helmholtz energy and allow for the calculation of all thermodynamic properties over the entire fluid surface including the gas phase, liquid phase, supercritical region, and equilibrium states. The mathematical structure of the new mixture models corresponds to the form chosen for the reference model GERG-2008 of Kunz and Wagner [J. Chem. Eng. Data 57, 3032 (2012)]. In this way, the equations can be implemented into the existing framework of the GERG-2008 model. The ranges of validity of the new equations correspond to the normal and extended ranges of validity of the GERG-2008 model.

We report, over an extended energy range, recommended angle-integrated cross sections for elastic scattering, discrete inelastic scattering processes, and the total ionization cross section for electron scattering from atomic indium. In addition, from those angle-integrated cross sections, a grand total cross section is subsequently derived. To construct those recommended cross-section databases, results from original B-spline R-matrix, relativistic convergent close-coupling, and relativistic optical-potential computations are also presented here. Electron transport coefficients are subsequently calculated, using our recommended database, for reduced electric fields ranging from 0.01 Td to 10 000 Td using a multiterm solution of Boltzmann’s equation. To facilitate those simulations, a recommended elastic momentum transfer cross-section set is also constructed and presented here.
