Steric effects in the chemiluminescent reactions of metastable Ca~*(~3P) atoms with isomeric alkyl halides

摘要

In the previous paper steric effects in the chemiluminescence reactions of metastable calcium atoms with isomeric propyl halide have been studied. Substantial differences in the CaCl(B~2∑) / CaCl(A~2II) branching ratio were found with isomeric variation of the targets. This has been a motivation for research presented in this work. Reactions of metastable calcium atoms in the metastable ~3P_J states with all commercially available normal and branched alkyl halides were studied in a beam-gas arrangement. Chemiluminescence spectra of alkaline earth monohalides were observed for calcium reactions. Total collision and chemiluminescence cross sections were measured.
