Structural and energetic properties of the Br--C2H2 anion complex from rotationally resolved mid-infrared spectra and ab initio calculations

Abstract

The properties of the proton bound Br--C2H2 complex revealed through mid-infrared vibrational predissociation spectroscopy and ab initio calculations were studied. It was found that the mid-infrared vibrational predissociation spectrum of the studied complex is consistent with a linear, proton-bound complex. Rotationally resolved features were observed in the v3 band that have an onset at a specific J′ value.
