Abstract

Sub-Doppler optical-optical double-resonance spectra of SrF were recorded using two single-mode cw dye lasers. Via the intermediate state B 2Σ+, the F 2Σ+ and G 2Π states were observed in the 32000 to 35000 cm-1 region above the ground state. The (1, 0), (2, 0), and (3, 0) bands of the F 2Σ+-B 2Σ+ transition and the (0, 0) band of the G 2Π-B 2Σ+ transition were rotationally analyzed. Rotational and vibrational constants for the F 2Σ+ state and rotational constants for the G 2Π state are reported.
