Rotational Spectra of NeCO2 Isotopomers
Abstract:
Rotational spectra of seven isotopomers of the weakly bound complex NeCO2, i.e., NeCO2, 22NeCO2, Ne13CO2, 22Ne13CO2, Ne18O13CO, Ne17OCO, and 22Ne17OCO, were measured using a pulsed molecular beam Fourier transform microwave spectrometer. Rotational and centrifugal distortion constants as well as the nuclear quadrupole coupling constants of 17O in Ne17OCO and 22Ne17OCO were determined. The obtained constants were used to derive structural and force field information. The parameters obtained are discussed, and compared with those of other, previously measured, rare gas-CO2 complexes. The 17O nuclear quadrupole coupling constants were analyzed and interpreted in terms of the angular anisotropy of the intermolecular potential energy surface. Copyright 1998 Academic Press.

As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are slanted or...
