摘要：

The technique of direct laser absorption spectroscopy in fast ion beams has been employed for the determination of absolute integrated band intensities (Sv0) for the ν3 fundamental bands of H 3O+ and NH4+. In addition, the absolute band intensities for the ν1 fundamental bands of HN 2+ and HCO+ have been remeasured. The values obtained in units of cm-2 atm-1 at STP are 1880(290) and 580(90) for the ν1 fundamentals of HN2+ and HCO+, respectively; and 4000(800) and 1220(190) for the ν3 fundamentals of H3O+ and NH 4+, respectively. Comparisons with ab initio results are presented. © 1990 American Institute of Physics.
