We calculate the excitation rates of the 5 [sup 2][ital D][sub 3/2] and 5 [sup 2][ital D][sub 5/2] states of rubidium through the simultaneous absorption of two photons of different frequencies by the ground 5 [sup 2][ital S][sub 1/2] state. We include spin-orbit effects in the contribution of the 5[ital P] and 6[ital P] states, situated between the initial and final states, which give rise to the resonance structure in the two-photon spectrum. We indicate how our results can be used for the case in which the transition takes place between states with specified total angular momenta [ital F], for both [sup 85]Rb and [sup 87]Rb. For the case of counterpropagating photons with the same frequency, our results are compared with existing experimental data.
