Effect of reagent alignment on the product state distribution in the reaction Sr+HF(v=1, j=1)→SrF(v′, j′)+H

Laser-induced fluorescence spectra of SrF from the reaction Sr+HF(v=1,j=1)→SrF(v′,j′)+H have been measured for two alignments of the molecular axis of HF favoring either end-on or side-on attacks. We find at the studied collision energies, Etr=217 and 279 meV, a significant but small influence of the alignment on the intensity of the four bandheads associated with v′=0, 1, 2, and 3.
