摘要：

The molecular-beam optical Stark spectrum of the A 2Π(ṽ = 1)-X 2Σ+ (v = 0) band system of ScO has been recorded and analyzed. The experimentally determined permanent electric dipole moments of the A 2Π3/2, A 2Π 1/2, and X 2Σ+ states are 4.06(3), 4.43(2), and 4.55(8) D, respectively. The determined hyperfine parameters for the A 2Π state are α = 135(1) MHz, d = 177(2) MHz, and eQq0 = - 83( 12) MHz. The spectroscopic parameters are interpreted in terms of plausible models for the electronic nature of the A 2Π and X 2Σ+ states and are compared with theoretical values. © 1990 American Institute of Physics.
