Abstract
Excited vibrational levels in the X 2Σ+ state of CaOH and CaOD have been observed via dispersion of laser induced fluorescence from selectively populated rotational levels of the A 2Π (100) state. The rotational structure of the (100), (200), (300), and (020) levels has been analysed for both molecules; for CaOH, the (400) level was also observed. The X 2Σ+ (020) level is split into 2Δ (l = 2) and 2Σ+ (l = 0) components with spacings of 24·369 and 17·183 cm-1 for CaOH and CaOD, respectively. Vibrational term values and rotational constants were determined for all the observed levels, and are based on an accuracy of better than 0·05 cm-1 for the measured line positions of the resolved fluorescence.Keywords
