Quantum mechanical analysis is presented on the control of the vector properties of the photoproducts by vibrationally mediated photodissociation of OH. The angular distributions and alignment of O(P-3) fragments are calculated near isolated and overlapping asymmetric resonances. The vector properties depend very sensitively on the vibrational levels (nu(i) = 0-4) of the initial X (2) Pi state. The variations of the anisotropy parameters as a unction of the excitation energy near the asymmetric resonances change markedly depending on nu(i). The widths of the variations tend to increase with increasing nu(i), which is very similar to the corresponding behaviors of the product branching ratios studied earlier [J. Chem. Phys. 104, 1912 (1996)], indicating that nu(i) could be a useful tool for choosing the proper linewidths in the experiments for the control of the product branching ratios, angular distributions, and nz distributions near asymmetric resonances. It is also found that the vector properties may exhibit splitting of the overlapping resonances for high nu(i), in contrast to scalar properties.
