The deperturbation analysis of ReN and nonadiabatic dissociation dynamics of BrCl and BrNO are reported. In the case of ReN, couplings between different electronic states changes apparent molecular properties such as rotational constants and excited state lifetimes. An experimental approach which enabled us to separated the contributions to the mixed states from specified energies and the spin-orbit branching ratio was measured as a function of the excitation energy. The correlation of the spin-orbit states of the photofragments was established. Such observations enabled us to establish nonadiabatic dissociation mechanisms. In both the spectroscopy and dissociation dynamics studies, the coupling between the nuclear and electronic degrees of freedom was investigated.
