Reactions involving reactive species produced in electric discharges are frequently characterized by the emission of visible light of many different colors. Some typical afterglows and atomic flames have been photographed, and the observed colors (or spectral distributions) are discussed with regard to the reactions from which they arise. Laboratory studies of this sort are helpful for the understanding of the energy transfer processes which occur in flames, in electrical discharges, and in the upper atmosphere.

The infrared spectrum of the v2+v6 band of C13C12H6 has been analyzed and a value of B0= 0.64865 ±0.00005 cm−1 determined. When this value is combined with that found in recent work on isotopically normal ethane, a “rs” value of 1.527±0.004 A for the carboncarbon bond distance is obtained. (Uncertainties are probable errors.)

Self-Broadening of Carbon Monoxide in the 2 v and 3 v Bands * 一氧化碳在2v和3v波段的自展宽*
Journal of research of the National Bureau of Standards. Section A, Physics and chemistry
Pub Date : 1963-05-01 DOI: 10.6028/jres.067A.022

The self-broadening of carbon monoxide has been measured for the 2 v and 3 v bands with pressures up to 3.5 atmospheres. A grating spectrometer of high resolving power was used for the measurements and the correction for finite slits was small. The corrections varied from 3 to 20 percent for the different conditions of measurement. The half-widths per atmosphere, γ°, decreased from 0.089 cm−1 for |m| = 1 to 0.053 cm−1 for |m| = 21. The half-widths are compared with those obtained by other investigators and it is shown that the results reported in this work fall in between the self-broadening values previously obtained.
在2v和3v波段，在3.5个大气压下测量了一氧化碳的自展宽。采用高分辨率的光栅光谱仪进行测量，有限狭缝的校正很小。在不同的测量条件下，校正值从3%到20%不等。每大气半宽度γ°从|m| = 1时的0.089 cm−1下降到|m| = 21时的0.053 cm−1。将半宽度与其他研究者获得的结果进行了比较，结果表明，本工作报告的结果落在先前获得的自展宽值之间。

The NBS Thermal Neutron Flux has been calibrated in terms of the gold thermal neutron capture cross section. The effective thermal neutron (below cadmium cutoff energy) flux density is estimated to be 4307 ± 2 percent n/cm2 sec in September 1961. This figure is in agreement with a recent value quoted by the NBS.

Thermodynamic data on the n-paraffins from n-C6H14 through n-C18H38 have been used to obtain values for the specific heat, entropy, enthalpy, and Gibbs free energy of a large, ideal CH2-chain crystal from 0 to 420 °K and of the liquid above 200 °K. Analytical expressions are given for the properties of the crystal and liquid above 200 °K. For the crystal, a modified Einstein function was used to adjust the melting temperature to 414.3 °K. Values between 975 and 1025 cal/mole for the heat of fusion were found to be the ones most consistent with the data. Comparison of the results with polyethylene data shows reasonable agreement.

通过 n-C6H14 至 n-C18H38 正石蜡的热力学数据，我们获得了 0 至 420 °K 的大型理想 CH2 链晶体和 200 °K 以上液体的比热、熵、焓和吉布斯自由能值。对于高于 200 °K 的晶体和液体的性质，给出了分析表达式。对于晶体，使用修正的爱因斯坦函数将熔化温度调整为 414.3 °K。研究发现，熔化热介于 975 和 1025 卡/摩尔之间的数值与数据最为吻合。将结果与聚乙烯数据进行比较，结果显示两者吻合。

In connection with an investigation of the correlation between structure and reactivity of eugenol isomers, o-eugenol, 3-allyl-2-methoxyphenol and chavibetol were synthesized. A five-step synthesis was found to be most suitable for the preparation of 3-allyl-2-methoxyphenol. An improved separation of chavibetol from eugenol was achieved by gas chromatography.

Visual observation of the freezing and melting of compounds in cells used for the determination of purity has uncovered some heretofore unexpected behavior. This behavior has been correlated with certain difficulties experienced in the measurement of purity, particularly when the sample is very pure. Means for partially reducing these difficulties are proposed and procedures for increasing the accuracy of purity measurements are described.

Measurements have been made of the frequencies of the infrared absorption lines of CO2 in the region from 1850 cm−1 to 2150 cm−1. Observations were made at various pressures and pathlengths up to a maximum of 72 meter-atmospheres. Vibration-rotation constants were obtained characterizing the transitions 111c0–000, 111d0–000, 031c0–000, 031d0–000, 200–011c0, I22c0–011c0, 122d0–011d0 for C12O2. The 111c0–000 band due to the C13O2 molecule was also measured.

Analysis of Families of Curves 曲线族的分析

A systematic approach is presented for fitting empirical expressions to data depending on two variables. The problem can also be described as the simultaneous fitting of a family of curves depending on a parameter. The proposed method reduces a surface fitting problem to that of fitting a few functions of one variable each. First, the surface is expressed in terms of these one-variable functions, and using an extension of two-way analysis of variance, the accuracy of this fit is assessed without having to determine, at this point, the nature of the one-variable functions. Then, the one-variable functions are fitted by customary curve-fitting procedures. For illustration, the method is applied to two sets of experimental data.
一个系统的方法提出拟合经验表达式的数据取决于两个变量。这个问题也可以被描述为依赖于一个参数的一系列曲线的同时拟合。提出的方法将曲面拟合问题简化为拟合一个变量的几个函数的问题。首先，用这些单变量函数来表示曲面，并使用双向方差分析的扩展，评估这种拟合的准确性，而不必在此时确定单变量函数的性质。然后，用常规的曲线拟合程序对单变量函数进行拟合。为了说明，将该方法应用于两组实验数据。
