Laser magnetic resonance of the v = 1←0 transition of the PD (3Σ−) radical

Abstract
Sixteen LMR spectra for the low N (N′, N″⩽3) transitions of the vibration (v = 1←0) band of PD (X 3Σ−) were observed by using seven 12C 16O laser lines. Analysis has yielded rotational, spin–spin, and spin–rotation constants for the v = 0 and 1 states and the band origin. The band origin ν0 has been determined to be 1653.2858(36) cm−1.
