A theoretical analysis is presented for the photodissociation processes of SH to S(3P) and S(1D). Transition dipole moments from the ground X 2Π state to the A 2Σ+, Σ−2, Δ,2 2 2Π states are computed by the effective valence shell Hamiltonian method. Two frame transformation matrices are constructed and used to describe the correlations between the two sulfur atomic terms [S(3P) and S(1D)] and the adiabatic Born–Oppenheimer molecular states. Very interesting dynamics of quantum interference effects and asymptotic interactions are found. At energies between the thresholds to the S(3P) and S(1D) limits, the resonances are mostly Lorentzian with more or less constant S(3Pj,j=0,1,2) branching ratios. The effects of the intrastate interactions between the repulsive states are predicted to be very strong. At energies above the threshold to S(1D) limit, quantum interferences between the dissociative pathways through the optically bright repulsive states (A 2Σ+, Σ−2, Δ,2 and 2 2Π states) are predicted to give asymmetric resonances of multichannel character. Partial cross sections to the triplet sulfur fine structure states S(3Pj,j=0,1,2) exhibit different degrees of asymmetry and, consequently, the S(3Pj,j=0,1,2) branching ratios display strong variations across the asymmetric resonances, suggesting the possibility of controlling the product distributions by scanning the excitation wavelengths across a single asymmetric resonance in a one-photon excitation process. At higher energies, the interference between the two direct dissociation routes (by A 2Σ+ and Σ−2 states) is shown to produce highly oscillatory variations of the total cross section for dissociation to S(3P) and of the branching ratios of S(3Pj,j=0,1,2).
