Interference between dissociating states inH2O2and HOCl causes orientation of OH diatomic products

Abstract

${\mathrm{H}}_{2}{\mathrm{O}}_{2}$ and HOCl were dissociated using circularly polarized light at wavelengths 330--370 nm, and angular-momentum polarization of OH ${(}^{2}\ensuremath{\Pi})$ products was measured using laser induced fluorescence. The OH $(J=0.5)$ products exhibit orientation of angular momenta resulting from interference between excited dissociating states of the parent molecules.
