Abstract

A new method of analysis for determining the rate constants of vibrational relaxation has been developed. Linearization of the equations of regression makes it possible to resolve the various problems and disadvantages of the conventional non-linear least-squares analyses. Not only the rate constants but also the relative detection sensitivities of different vibrational levels can be determined without information on photochemical parameters by which excitation spectra are usually corrected. Consequently, nascent vibrational distributions of the molecules produced in photolyses or chemical reactions can also be determined from the profiles recorded even under multiple collision conditions. The principles of the new method and how some advantage is offered are described, along with the comparison with the conventional analyses. Application of the method to practical schemes is also shown in detail.
