The scientific clause is devoted to complex examinations of optical properties of micro crystals of alkali-halides simulative an atmospheric salt aerosol. In laboratory requirements the interactions in system much less thanmicro crystals of salts gas phasemuch greater than were explored at superimposition of high-energy fields. Thus the scale of radiation and cold air plasma was utilized ultraviolet, X-ray. Is shown, that the presence of high-energy fields gives in interaction of micro crystals and gas phase. At interaction the chemical composition, structure and optical properties of salt particles changes. The scientific clause is devoted to study of optical properties of salt particles mainly in infrared range of a spectrum. The purpose of operation is the study of transformation of salt micro crystals and its communications with optical parameters.
