Photodissociation dynamics of cumene hydroperoxide at 248 and 193 nm producing (C 6 H 5 )(CH 3 ) 2 CO (CumO) and OH fragments has been investigated by measuring laser induced fluorescence spectra of the OH fragments, which are produced exclusively in the ground electronic state. The measured energy distributions among the fragments are f r (OH) ) 0.03, f t ) 0.49, f int (CumO) ) 0.48 and f r (OH) ) 0.03, f t ) 0.18, f int (CumO) ) 0.79 at 248 and 193 nm, respectively, and negligible vibrational excitation in OH was observed at both wavelengths. At 248 nm, slightly negative µ-V and positive V-J vector correlations were observed by analyzing the Doppler profiles of the rotationally resolved OH spectra, whereas no vector correlations were observed at 193 nm. From the measurements, detailed photodissociation dynamics of cumene hydroperoxide is discussed compared to the case of tert-butyl hydroperoxide previously studied.

The photodissociation dynamics of tert-butyl hydroperoxide at 193 nm was investigated by measuring rotationally resolved laser-induced fluorescence spectra of OH fragments. The OH fragments are exclusively produced in the X( 2 Π 1/2,3/2 ) state. From the spectra, the fraction of the available energy distributed among the products was found to be f r (OH) ) 0.04, f t ) 0.56, f int (t-BuO) ) 0.40, with negligible fraction of OH being in excited vibrational states. In addition, vector correlations were obtained by analyzing the Doppler profiles of the spectra. The detailed dynamics of the dissociation process is discussed compared to the dissociation of H 2 O 2 .
