WEAK HYDROGEN-BONDING IN ETHANOL AND WATER SOLUTIONS IN LIQUID HYDRIDES OF GROUP IV-VI ELEMENTS (SIH1, GEH4, PH3, ASH3, H2S, AND H2SE) .2. IR SPECTROSCOPY OF HYDROGEN-BONDING IN SOLUTIONS CONTAINING WATER IN HYDRIDES

The results of an IR spectroscoic study of solutions of water in liqui d hydrides of the group V and VI elements (PH3, AsH3, H2S, and H2Se) i n the temperature range from T-b of hydride up to 290 K are presented. The solubility of water in liquid SiH4 and GeH4 is lower than the det ection limit of infrared spectroscopy. The spectral parameters of the stretching and bending vibration bands of water are measured. The form ation of weak hydrogen bonds between the molecules of water and hydrid es takes place. To account for the shape of the stretching band of wat er, 1:2 complexes with hydrides are postulated to be present in these solutions. Their binding energy is estimated. Values of the Gutman don or numbers of the hydrides in the liquid phase are given.
