Abstract

This review covers some modern applications of statistical methods in the analysis of complicated molecular spectra, obtained usually with laser excitation. Among the available fluctuation measures, special emphasis is given to the nearest neighbour separation and spectral rigidity measures, and attention is called to the power spectrum (or statistical Fourier-transform) method. From the high-resolution spectroscopic techniques used to obtain spectra of highly vibrationally excited molecules, the stimulated emission pumping (SEP) scheme is very successful in simplifying the high excitation regions. Examples of SEP applications are given, especially to acetylene, in greater details. Finally the role of molecular rotation in molecular dynamical and statistical studies is stressed.
