N2 - The J=4-3,J=5-4, andJ=6-5 pure rotational transitions in the ground X 1Σ+ state of yttrium monofluoride, YF, have been recorded by molecular beam millimeter-wave optical pump/probe spectroscopy. This study demonstrates that high resolution (<100 kHz fwhm) millimeter-wave measurements of high temperature refractory compounds can readily be obtained via the combination of optical detection and high temperature effusive oven molecular beam sample preparation. The measurements performed here provide an improved determination of the ground state rotational constants B=8683.65 (1) MHz, and D=0.0079 (2) MHz.
