    "abstract": "Nonlinear effects in emission and absorption spectra of gaseous systems are\nconsidered. It is shown that level splitting can be detected spectroscopically\neven if it is below the Doppler width. Conditions for distinguishing\ninterference effects from those due to nonequilibrium velocity distribution are\ndetermined. In the case of large Doppler broadening the correction for atomic\nmotion is equivalent to the substitution of an \"effective immobile atom\" for\nthe moving atom ensemble. The spectral manifestation of nonlinear effects is\nanalyzed in detail. The influence of nonlinear interference effects on the\ngeneration characteristics in the presence of external field is investigated.",
