    "abstract": "Infrared-infrared double resonance measurements of the $\\nu_3$ absorption\nband of $SF_6$ using a $CO_2$ TEA laser radiation have been carried out. The\nresults obtained in the present and in some earlier works are discussed taking\ninto account existence of a wide component of lines, nondegenerative four\nphoton mixing (NFPM) and time invariance violation in the photon-molecule\ninteractions. It is proposed to use the NFPM effect in investigations of the\nshape of the optical transition in polyatomic molecules and especially for\nevaluation of the homogeneous width of the wide component of lines. The need\nand problems of experimental study of existing effects of the T-invariance\nviolation in optics are discussed.",
