From your expression, compute the temperature of the HCl sample. Ground vibrational frequency (v 0) was equal to 2883.881 ± 0.07 cm-1 for HCl and 2089.122 ± 0.12 cm-1 for DCl and is the main factor in describing vibrational aspects of each molecule and initial parameters of the spectra. ; Wagman, D.D. ABSTRACT: FTIR spectroscopy was used to analyze rotational-vibrational transitions in gas-state HCl and DCl and their isotopomers (due to 35 Cl and 37 Cl) to determine molecular characteristics. Start with R(0), R(1), etc., and P(1), P(2), etc. (compare C-C, C=C, C≡C ) (c) The number of vibrational modes depends on how many atoms are there in the molecule. � See Tyndall j m�0J 0J H*
