The chemiluminescent reactions Sr + NOCl-->SrCl(A,B) + NO are studied under the single collision conditions in a beam-gas arrangement. The product rotational alignment [P-2( (J) over cap'.(k) over cap)] = -0.40 +/-0.05 for SrCl(B) is obtained from Sr+NOCl chemiluminescent reactions. In addition, the electronic state branching ratio and the product vibrational state distribution have been roughly estimated by simulating the chemiluminescent spectra of SrCl. Quasiclassical trajectory (QCT) calculations for the Sr+NOCl reaction as a three-body system have been carried out. The calculated results agree;well with the experimental ones.
