Effect of Reagent Vibrational Excitation on Product Rotational Polarization in Reactions Li + DF (v=0-3, j=0)→ LiF(v', j') + D

摘要

A quasiclassical trajectory calculation is carried out to investigate the effect of reagent vibrational excitation on product rotational polarization in the reactions Li + DF (v=0-3, j=0) → LiF(v', j') + D. It is found that the reagent vibational excitation highly enhanced the product rotational alignment, however, the enhancement is not monotonically increasing with the gradual increase of the vibrational quantum number from v=0 to v=3. The product rotational orientation varies from the negative to positive direction of y axis with the increasing vibrational quantum number from v=0 to v=3.
