β¦ Synopsis
The product polarixation in the beam-gas chemiluminescent reactions Ca( 'Pi) + RI-CaI*+R for different initial Ca eleo tronic orbital alignments are both probed experimentally and calculated with the DIP extension of the DIPR model (the direct interaction with product repulsion (DIPR) model, with product repulsion distributed as in photodissociation (DIP) model). The experimental results show that the product rotational aligmnent is independent of the Ca( 'Pi) orbital alignment and that the distribution of the product rotational vector becomes less anisotropic as the number of carbon atoms in R increased. The reagent alignment sensitivity factors of the reaction Ca( 'Pi) +CH31-CaI*+CH3 are ako investigated.
