Paper Abstract

The main tendencies in the up-to-date development of experimental methods of molecular spectroscopy of the atmospheric gases are connected with the increase of spectral resolution, absorption sensitivity of instrumentation as well as the use of new spectral regions and wider applications of research. The high monochromaticity of laser emission used in facilities for atmospheric studies, in combination with the selectivity of atmospheric absorption spectra in the optical range, and large dynamic range in the variations of absorption coefficients (from 10-4 cm-1 at the centers of strong lines down to 10-8 cm-1 for weak lines in the atmospheric transmission windows) require qualitatively new spectroscopic information for solving many practical problems of atmospheric optics. This lecture deals with the discussion of investigations by means of the highly sensitive methods of the laser absorption spectroscopy (intracavity, opto-acoustic, and photometric) as well as of the quantitative data on the highly excited molecular states obtained.
