Abstract

A pump/probe microwave-optical double resonance experiment has been performed on calcium monohydroxide, CaOH, using the technique of laser ablation/supersonic expansion for production of the compound. Frequencies associated with the three lowest pure rotational transitions in the (0,0,0) X̃2Σ+ vibronic state were observed with a resolution of <80 kHz (FWHM) and were analyzed to give the spectroscopic parameters (in MHz): B = 10023.0841(7), D = 0.01154(5), γ = 34.7593(10), bF(H) = 2.602(3), c(H) = 2.053(10). The proton hyperfine interactions were interpreted in terms of a molecular orbital description for the X̃2Σ+ state.
