The role of the electron translational factors (etf) in the semiclassical theory of charge transfer is addressed with respect to orientation effects and possible propensityrules in s-p and p-p capture processes. It is shown that orientation effects can be understoodin the light of the intuitive classical ‘rolling ball’ and ‘velocity matching' arguments andanalysed using the Larsen-Taulbjerg first-order approximation to the etf. Emphasis isplaced on investigating resonant p-p transfer which is a crucial test case for the effects ofetf on orientation dependences. The predictions are exemplified by four-state closecoupling calculations for Na(3p1m)) + Na+→ Na+ + Na(3p1m) resonant transfer taking fullaccount of etf. Some problems involved in comparing experimental data at small scatteringangles with theoretical predictions are discussed.
