Experimental and theoretical study of S 2p and C 1s generalized oscillator strengths in CS 2

Abstract

The generalized oscillator strength profiles in the momentum transfer range ( K) of (2 a.u. −2 < K 2 < 30 a.u. −2) for the most intense resolved S 2p, and C 1s transitions of carbon disulfide (CS 2) are presented. Optical oscillator strengths and generalized oscillator strength profiles have been calculated for vertical excitation from the ground X 1 Σ g + electronic state to several C(1s) and S(2p) inner-shell electronic excited states of CS 2, using high level ab initio (HF-CI) calculations. The experimental and computed GOS profiles of CS 2 are compared and found to be generally in reasonable agreement.
