Abstract
The B̃ 2Σ+–X̃ 2Σ+ transitions of BaOH and BaOD were studied by the technique of dye laser spectroscopy. The 000–000 and 001–000 bands of BaOH and 000–000 band of BaOD were rotationally analyzed. The B̃ 2Σ+ state is perturbed by the à 2Π state and each parity (e/f) component of the B state was fit separately. BaOH is a linear molecule with r0(Ba–O)=2.201 Å and r0(O–H)=0.923 Å. The X̃ 2Σ+ vibrational frequencies for BaOH (BaOD) are 492.4 (482.4) cm−1 for Ba–O stretch and 341.6 (257.6) cm−1 for the bend.Keywords
