Photodissociation Dynamics of Allyl Alcohol at 193 NM

초록

Photodissociation of allyl alcohol at 193 nm has been investigated by measuring laser-induced fluorescence spectra of OH fragments that are exclusively produced in the ground (2∏) electronic state. From the spectra, rotational and vibrational population distributions in OH and energy partitioning among fragments have been obtained. The measured average rotational energies in OH are 1430/1320 cm-1 and the vibrational population ratio is 0.89/0.11 for v = 0/1, respectively. In addition, no polarization dependences upon dissociation have been observed. It is suggested that the dissociation takes place in the excited triplet surface via curve crossing from the initial π → π*c=c transition.
