The millimeter-wave spectra of furan, pyrrole, and pyridine: Experimental and theoretical determination of the quartic centrifugal distortion constants
Abstract
The ground state rotational spectra of furan, pyrrole, and pyridine have been investigated in the millimeter-wave range. High J transitions ( J<60) have been measured and accurate rotational and centrifugal distortion constants have been determined. The results of the analysis are sufficiently accurate for the prediction of all strong transitions throughout the millimeter-wave range. The experimental quartic centrifugal distortion constants are compared with the values calculated from a quantum chemical force field.
