The photodissociation of D2O was carried out at excitation wavelengths of 1216, 1236, and 1302 Å. The distribution of the excess energy to rotational and vibrational degrees of freedom of the product OD was determined by an investigation of the OD 2Σ+ emission. The population of the highest allowed rotational levels was observed with results similar to those obtained for H2O. It has been found that the two spin components of the higher rotational levels were unequally populated. An attempt is made to account for this anomalous population distribution.
