Molecular Beam Studies of Bimolecular Reactions: F + H₂ and Li + HF

Using reactions of F + H 2 → HF + H and Li + HF → LiF + H as examples, the application of the crossed molecular beams method in the investigation of dynamics of bimolecular chemical reactions is described. Most of the discussions are centered on the angular distributions of reaction products and their implication to the relation between potential energy surface and reaction dynamics.
