Abstract
A new method has been developed for determining the correlation of a product molecule with the partner product molecule formed in the same chemical event. Doppler-shift measurements are used in conjunction with level-specific detection of scattered photofragments by laser-induced fluorescence. The technique is demonstrated in the photodissociation of H2 O2 where Doppler profiles of OH absorption lines are used to determine the mean rotational state of the OH partner molecule coincidently formed in the same fragmentation process.
