✦ Synopsis

The (3000) Ge-H stretching overtone band of germane, GeH, (conventionally described as 3u,) has been observed near 6130 cm-' by Fourier transform infrared spectroscopy with a resolution of 0.01 cm-i. The rotational structure shows no sign of the tetrahedral splitting patterns normally characteristic of a spherical top. Instead the band exhibits a striking pseudo-symmetric-top structure. This had been predicted by Halonen and Robiette as the limiting case of a spherical top showing local-mode behaviour. The present results represent the first observation of this phenomenon, ' Royal Society Visiting Fellow, on leave from

The FTIR spectrum of H 3 SiD in the 4100-4500-cm 01 region was recorded at Doppler-limited resolution, and four bands were studied. At lower wavenumbers, two strong bands, which in the local mode picture can be assigned to (200, E) (n 0 Å 4308.5667 cm 01 ) and (200, A 1 ) (n 0 Å 4307.8441 cm 01 ), w
