Dependence of Product Alignment on Product Vibration for the Sr（³P）+Cl₂ Chemiluminescent Reaction

The dependence of SrCl（B） state alignment on vibrational level was stu ided by means of the product polarization for the beam-gas chemiluminescent reaction Sr（³P）+Cl₂→SrCl（B²Σ⁺）+Cl under single collison condition. Polarization values display a marked variation with wavelength. At lower vibrational level, SrCl（B） product becomes slightly more depolarized with increasing vibrational energy. This trend reverses at higher vibrational levels and polarization begins to rapidly increase with increasing vibrational energy. The pattern is duplicated in five vibrational sequences.
