Notes:
Rotationally resolved, vibrational predissociation spectra of the HN+2–He complex have been recorded in the region of the N–H stretch (3100–3200 cm−1). The complex appears to be linear. Fitting of the measured lines to the pseudodiatomic expression ν=ν0+(B'ν+B‘ν)m +(B'ν−B‘ν–D'ν+D'ν) m2−2(D'ν+D‘ν)m3 −(D'ν−D‘ν)m4 yields the following constants: ν0=3158.419±0.009 cm−1, B‘=0.3517±0.0005 cm−1, D‘=(5.8±0.5)×106 cm−1, B'=0.3579 ±0.0005 cm−1, D'=(3.9±0.6)×106 cm−1. The data support a proton bound He–HNN+ structure, with a 1.72 A(ring) vibrationally averaged intermolecular bondlength, and an approximate intermolecular stretching frequency of 150 cm−1. © 1995 American Institute of Physics.
