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
