摘要：

The fine and hyperfine resolved state-to-state rate coefficients for the rotational (de)excitation of C3N by collision with helium are computed. To this aim a 2D potential energy surface is calculated for this system. The recoupling method is used to obtain the fine and hyperfine structure resolved rate coefficients from spin-free close-coupling calculations. These results are compared with those given by the infinite-order sudden approximation and the M-randomizing limit. General propensity rules for the transitions are also found and analysed.
