✦ Synopsis

The streuzhing mode in thin (50 nm), free, liquid fiJms has been e xamined by means of iaser intensity fluctuation sprc- toscopy (heterodyne configuration). The power density spectra of the scattered intensity fluctuaticms show mvrima ~ZX the MHz region, indicating the propagating character of the mode_ The peak frequencies are related to the surface tension of the f&u.

We have investigated the vibrational relaxation of the OH impurity stretch mode in amorphous SiO 2. At low temperatures, a short relaxation time of ~-10-l0 s is found that varies strongly across the inhomogeneously broadened absorption line. The inhomogeneous broadening is caused by a site-dependent
