Analysis on the Impact of Discharge Frequency on the Signal Intensity in the Velocity Modulation Technique

LI Song (Yangtze University,Jingzhou 434023)  
Absorption spectra of 220F2←331F2 and 220F1←331F1 transitions of H2O+ was recorded with the velocity modulation spectroscopy under different discharge frequencies.Impact of discharge frequency on the signal intensity and their relationship was analyzed.Optimal control of discharge frequency was proved to be a key point to the detection of molecular ions in the velocity modulation technique.
