Results of high-resolution molecular spectroscopy investigations conducted at IAO SB RAS during the last five years are outlined in this brief review. We consider theoretical problems of vibrational-rotational spectra of basic molecules of atmospheric gases, spectral line contours, problems of the atmospheric continuum absorption, and databases of molecular spectral characteristics in gas phase. In the section of experimental investigations, the main attention is devoted to results obtained by the Fourier spectroscopy methods using laser diodes as a radiation source, as well as results obtained at a Fourier spectrometer with a multipath 30-meter cell with computer control of optical path length under temperature and pressure variations of a gas under study.
