N2 - IR absorption spectra of monoisotopic 28SiH 4 and 76GeH 4 are studied in Ar and N 2 matrices at 10 K. It is shown that the absorption spectra of silane and germane are similar in the regions of the stretching v 3 and bending v 4 vibrations. Four groups of bands can be separated out in the spectra of each molecule: (1) narrow bands characteristic of the matrix isolation studies, (2) broad bands, (3) diffuse absorption with a large value of the spectral moment M* 2 the intensity of which increases upon annealing, and (4) bands of dimers the intensity of which increases quadratically with concentration. The spectra of 28SiH 4 and 76GeH 4 in nitrogen matrices contain a triplet in the stretching region and a doublet in the bending region, which is explained by the change in the molecular symmetry from T d to C 3V on passage from the gas phase to solid nitrogen.
