Abstract
We report the first direct observation of the vibration-rotation spectrum of the diatomic chromium-hydride in its X6Σ+ ground state by CO-Faraday laser magnetic resonance spectroscopy (LMR). Transitions of all four isotopomers attributed to the fundamental and the first hot band were detected. The spectra were analysed by a single least-squares fit using an effective Hamiltonian. A set of effective molecular parameters for the X6Σ+ ground state is given.
