摘要: Abstract The electron impact ion fragmentation of a hydrogen fluoride molecular beam excited by cw HF laser into the v = 1 vibrational level has been investigated with quadrupole mass spectrometer. ratio F + to signals is found increase linearly increasing degree excitation and decreasing energy. results are interpreted in terms Franck—Condon overlap ionic potential curves. These direct quantitative measurements demonstrate use spectrometer as probe beam.
