The fragmentation functions for the heavy mesons of [ital S] and [ital P] waves are calculated in the framework of perturbative QCD and the nonrelativistic quark model. The results are manifestly process independent. As applications, the production ratios for [ital P]-wave [ital [bar b]c] mesons to the [ital b[bar b]] production at high energy colliders are predicted. The spin dependence of the fragmentation functions for various states is discussed and the predicted results for the [ital D] ([ital D][sup *]) mesons are consistent with the recent experimental data.
