An infrared picosecond transient bleacbmg technique wa\_s used LO measure vibrational lifenmes (I;) of hydroxyl groups in fused silica over the temperature range 100-1450 K 7, decreucs from 109 to 15 ps in this range. The 7, remperakure dependence is compared co non-radrative relaxation theory for t
