摘要：
Spectroscopic properties of Ar-HCO+ have been studied by exciting the C-O stretch of the HCO+ chromophore. The ionic complex is generated in a slit jet expansion with subsequent electron impact ionization. The spectra are obtained by direct absorption spectroscopy using a tuneable diode laser and production modulation. The nu(3) band of the Ar-HCO+ is rotationally resolved and has a form consistent with a linear proton-bound complex. The band origin is at 2135.7073(4) cm(-1) which is 48.24 cm(-1) red-shifted compared to the value in free HCO+. (C) 1998 Elsevier Science B.V. All rights reserved.
