A second-quantization formalism has been used to obtain a general expression for the generalized oscillator strength (GOS) for inner-shell electron transitions between two open shells of any atom. The present formula together with the spin polarized technique of the random-phase approximation with exchange are then employed to investigate correlation effects in the GOS for the Na 2p{sup 6}3s({sup 2}S){yields}2p{sup 5}3s{sup 2}({sup 2}P) transition. Results are compared with those measured by Bielschowsky et al. [Phys. Rev. A 43, 5975 (1991)]. The present formula has also been used with Hartree-Fock wave functions to calculate the GOS's for the carbon 2s{sup 2}2p{sup 2}({sup 3}P){yields}2s2p{sup 3}({sup 3}P) and 2s{sup 2}2p{sup 2}({sup 3}P){yields}2s2p{sup 3}({sup 3}D) transitions. The calculated multiplet oscillator strengths for the two transitions are compared with the experimental values.
