ROTATIONAL ALIGNMENT OF PRODUCTS FROM NOCL+SR CHEMILUMINESCENT REACTION

The chemiluminescent reactions Sr + NOCl-->SrCl(A,B) + NO are studied under the single collision conditions in a beam-gas arrangement. The p roduct rotational alignment [P-2( (J) over cap'.(k) over cap)] = -0.40 +/-0.05 for SrCl(B) is obtained from Sr+NOCl chemiluminescent reactio ns. In addition, the electronic state branching ratio and the product vibrational state distribution have been roughly estimated by simulati ng the chemiluminescent spectra of SrCl. Quasiclassical trajectory (QC T) calculations for the Sr+NOCl reaction as a three-body system have b een carried out. The calculated results agree;well with the experiment al ones.
