✦ Synopsis

Rotational alignment of the product SrBr in the beam-gas reactions Sr + RBr (R= CH3, C2H5, n-C3H7, and i-C3H7 was studied in experiment and theory. The rotational alignment was probed by means of the polarized laser-induced fluorescence (PLIF) of the product. The distributions of the rotational vector become less anisotropic with the increment of the numbers of the carbon atoms in RBr. Moreover, a simple dynamical model was used to calculate the product rotational alignment. The theoretical results are in good agreement with the experimental ones.
