A new hydrochloric acid 2-0 band analysis: A two temperature study
A new study of the 2−0 band of the hydrochloric acid molecule is performed by high resolution Fourier-transform absorption spectroscopy in the near infrared region. The spectra were measured at two different temperatures, 293 K and 315 K, for different pressures at each temperature. The spectral linewidths were analysed in a two-step procedure, being first performed by directly measuring the linewidth and second by fitting each spectral line to a model line profile, using Gaussian, Loretzian and Voigt profiles. A study of the profiles that best describe the spectral line fits is carried out in this work. The behavior of the spectral lines self-broadening and their corresponding self-induced shifts were studied for different values of rotational quantum numbers. The analysis are performed for both isotopes of the molecule and the self-broadening and self-shift coefficients are presented.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
