摘要：
The effect of pressure broadening on the line shape of velocity modulation laser spectroscopy is considered here, which is induced by the collisions of the gas molecules. The old theory on velocity modulation spectroscopy is revised and new theory is setup to get the precise simulation of our experimental spectrum. It has been shown that the new theory agrees with experiments perfectly, and has potential applications in the investigation of the dynamics of the collisions of molecular ions and obtaining more precisely resolved spectrum.
