The charge transfer in collisions of C{sup 2+} ions with the HF molecule has been studied by means of ab initio quantum chemistry molecular methods followed by a semiclassical dynamical treatment in the keV collision energy range. The mechanism of the process, in particular its anisotropy, has been investigated in detail in connection with nonadiabatic interactions around avoided crossings between states involved in the reaction. The vibration of the molecular target has been analyzed and cross sections on different vibrational levels of HF{sup +} have been estimated in the Franck-Condon approximation.
