  • Abstract The state resolved photodissociation of rovibrational states of the fundamental symmetric stretch of water, H 2 O (1, 0, 0), and of the OH or OD stretch vibrations of HOD was studied using laser induced fluorescence and Doppler polarization spectroscopy. The control that the initially selected state exerts over the product state distribution, vector correlations and bond selectivity was demonstrated. The specific energy deposition via the lowest level of vibrational excitation leads to the enhancement of bond breaking and to structured rotational state distributions of the OH fragment which depends on the prepared rotational state of the parent. The correlations are close to the maximum attainable values expected for an idealized orientation where the transition dipole moment of the parent is parallel to the fragment angular momentum and perpendicular to its velocity. The …
