Abstract

In our previous article on CCl₄ in this Journal, we presented an investigation of the fine structure of the symmetric stretch of carbon tetrachloride (CCl₄) due to isotopic variations of chlorine in C³⁵Cl_x³⁷Cl_4-x. In this paper, we present an investigation of the contributions from both the v = 0 to v = 1 excitation and the v = 1 to v = 2 excitation. We report the calculation of spectral contributions from excited state vibrational transitions (hot bands). All calculations and discussion are appropriate for the undergraduate physical chemistry laboratory as either an independent dry lab or a supplement to a pre-existing vibrational spectroscopy lab.
