Vibrational lifetimes of the surface hydroxyl groups of zeolites (Y-type and mordenite) were measured in real time by pumpprobe absorption spectroscopy using picosecond IR pulses. The relaxation lifetimes of the OH (II= I ) groups of Y-type zeolites which give the OH stretching bands at 3625 and 354
