The effect of the detailed Raman cross section on the evolution of ultrashort solitons is considered. It is shown that the gain contribution leads to the self-frequency shift, whereas the phase contribution, which is usually determined by use of the Kramers-Kronig relations, has little visible effect. This result is consistent with the hypothesis that solitons are robust in the presence of Hamiltonian deformations.
