Transient absorption spectra were observed on vibrationally exciting the OD group of a water molecule D 2 O adsorbed on a acidic hydroxyl group of a zeolite. A transient absorption signal indicating a newly appeared surface species was observed. The lifetime of the newly appeared surface species was determined to be about 15 ps. The origin of this short-lived spectral feature was ascribed...
Vibrational relaxation (v = 1 → 0) dynamics of O-H stretching mode of bridging hydroxyl groups in a mordenite zeolite under interaction with Xe was studied by means of tunable picosecond infrared pump-probe experiment. The lifetime, T 1 , of isolated hydroxyl groups decreased from 169±4 ps (123 K) to 58±2 ps (183 K) by the effect of adsorbed Xe. The vibrational energy was transfered to the...
