Abstract: | Doppler-limited, laser-induced fluorescence spectra on the B1Σ+-X1Σ+ (v′ = v″ = 0 and 1) system of MgO have been obtained. The results of the optical analysis were merged with our microwave-optical double-resonance measurements to produce the following set of spectroscopic parameters for the B and X states, where the units are in cm?1, and the uncertainties represent 95% confidence limits: T′0.0 = 20003.594(2); B′0 = 0.58004(3); D′0 = 1.13(2) × 10?6; B″0 = 0.57198(3); D″0 = 1.20(2) × 106; T′1.1 = 20043.423(2); B′1 = 0.57528(4); D′1 = 1.14(11) × 106; B″1 = 0.56674(4); D″1 = 1.22(10) × 106. |
