✦ Synopsis

The gas-phare fundamental and overlone (o =l-7) spectra of de C-H svelching modes of the series M(CH3), (M = C, Si. Gc, Sn) have been retarded using intramti~y photoacoustic laser spec~~ovopy as well as standard infrared uxhmques. Absorption cross sections have been obtied for u = 5 and 6 of Lhe series. The change m frequency of the transitions and tie mass-dependent changes in imewidth are interpreted in lerms of a local mode description of vibrational overtones ' On ieave from Departamenlo de Quimica, Universidad Simbn Rolivk Aparlado 80659, Caracas 1081.
