Paper Abstract

Some years ago a new approach was proposed to investigate polyatomic molecules' spectra, where spectra were treated as an ensemble of all spectral lines. Statistical parameters of the whole ensemble have to be measured in this approach giving averaged information about spectral lines' distribution function and relaxation matrix. The approach appears to be very powerful giving qualitative information even for spectra with strongly overlapping lines. A theoretical model was developed to give physical meaning for measured values. That's why new information was obtained for polyatomic molecule spectra that could not be investigated previously due to problems of experiment and treatment. Thus some new effects were observed, such as line mixing and resonance behavior of collisional broadening and shifts.
