✦ Synopsis

The elrcuon impact ion fmgmcnmGon of ;1 hydrogen fluoride molecular bcnm cxciwd by a cw HI-laser into the u =I vibraional Irvrl has bsrn invc~~igawd wilh a quadrupolr mass spwlromrwr. The tilio or the F+ IO HF' ion signals is round IO increase linearly with increasing dsgrer ol exciralion and decreasing elccrron rncrgy. The result arc inwrprrwd in wrms or ths Fnnck-Condon ovulap with the ionic powntinl curvrs. Thrss direa quanlimlivr measursmenw dsmonswaw ths USL' or n rrmss spcaromrwr as a probr oC the drgrcr of vibraGonal cxcimlion 01 HF in a molcculnr beam.
