Abstract
We report the first direct observation of transitions between the strongly mixed low lying X1Σ+, a3Π and A1Π electronic states of 24Mg16O. The A1Π−X1Σ+ (0–2) band and the a3Π0.1−X1Σ+ (0–1) intercombination bands have detected. The measurements were performed with the CO laser Faraday laser magnetic resonance (LMR) technique in combination with a special oven set-up for the MgO production. The LMR data were fitted together with already published data to an effective Hamiltonian where the spin-orbit, orbit rotation and Zeeman interactions between these three electronic states are included directly. We determined the interaction parameters and obtained a set of effective deperturbed molecular parameters of MgO in the X1Σ+ (v = 0, 1, 2), a3Π (v = 0) and A1Π (v = 0) states. These parameters describe the LMR data within 7 × 10−4 cm−1 (21 MHz) on average, which corresponds to the experimental uncertainty.
