The near-infrared absorption spectra of H/sub 2/O trapped in solid argon and xenon were studied at 20 tained K. The spectra, taken at concentrations of H/sub 2/O to matrix of 1:600, exhibit structure which is analyzed in terms of the known rotational and vibrational constants of the H/sub 2/O molecule. The results show that in solid xenon and argon matrices, the monomer H/sub 2/O exists as two modifications, one of which is rotating in its ground vibrational state. The theoretical intensities for the spectral bands of H/sub 2/O gas at 20 tained K are calculated and shown to agree with the bands observed in H/sub 2/O-xenon. The changes in the observed intensities for other matrices are discussed. The changes in the spectra of the films when they are warmed to 35 tained K are shown and discussed. (auth)
