The rotational spectra of YO, LaO, ZrO, and HfO have been measured using a Fourier‐
transform microwave spectrometer in combination with a laser‐ablation source. Here, a Q …

Empirical line lists BRYTS for the open shell molecule 89Y16O (yttrium oxide) and its
isotopologues are presented. The line lists cover the six lowest electronic states:,,,,, and up …

We report an ab initio study on the spectroscopy of the open-shell diatomic molecule yttrium
oxide, YO. The study considers the six lowest doublet states, X2Σ+, A′ 2Δ, A2Π, B2Σ+ …

The YO molecules in gas-phase were formed by the reaction of the laser produced yttrium
plasma with molecular oxygen and subsequently cooled by free-jet expansion. The YO …

A molecular beam optical and rf–optical double resonance spectroscopic study of numerous
vibrational components in the A 2Π3/2–X 2∑+ subband of gas phase YO has been …

A molecular-beam-optical and rf-optical double-resonance study of the A 2n (v'= 0-2)-x
2~+(v"= 0-2) band systems of gas phase scandium monoxide has been performed. No …

YO bands are conspicuous in the spectra of S stars. The laboratory spectrum of the A 2 Π–X
2 Σ+ electronic transition has been recorded with a Fourier transform spectrometer using a …
