Photodissociation dynamics of morpholine at 193 nm was studied, using laser induced fluorescence technique. OH photoproduct was detected, though the parent molecule does not contain any OH group. The nascent OH radical was found to be in electronically and vibrationally ground state. Experimental results indicate that the major part, i.e., ~35% of the available energy is partitioned as the relative translational energy of the photofragments. Between the two spin–orbit states, ²II_3/2 and ²II_1/2, the latter is preferentially populated. The two Λ-doublet states are, however, found to be statistically populated. Based on both the theoretical and the experimental studies, a suitable reaction mechanism has been proposed for OH formation.
