Experimental equipment for studies of interaction of IR-radiation with liquid hydrides of groups IV-VI elements

The complex of special experimental apparatus for studies of interaction be tween IR-radiation and the thermally-stable volatile inorganic hydrides of groups IV-VI elements of the 2nd, 3rd and 4th periods in the liquid state a nd in the liquefied gas solutions is described. The main methods of solute concentration and integral absorption coefficients measurement are consider ed. The results of studies of IR-radiation absorption by volatile inorganic hydrides such as SiH4, NH3, PH3, AsH3, H2S, and H2Se in the liquid state a nd in the cryogenic solutions are presented. Using intensity, frequency and IR-absorption band contour data, the main mechanisms of intermolecular int eractions in these liquids are discussed. (C) 2000 Published by Elsevier Sc ience B.V.
