Laser spectroscopy of YBr: rotational analysis of the C1Σ–X1Σ system†
Abstract
The (0,0), (0,1), (0,2), (0,3), (1,2), (1,3), (1,4) and (2,4) bands of the C1Σ–X 1Σ transition of YBr, between 720 and 765 nm, have been studied using the technique of laser vaporization/reaction with supersonic cooling and
= 0–2 levels of the C 1Σ state and the
= 0–4 of the X1Σ state. The equilibrium bond length of the C1Σ state has been determined to be 2.6087(2) Å.
