Microwave and Millimeterwave Spectrum of Monofluoracetonitrile-¹⁵N (CH₂FC¹⁵N). A Contribution to Molecular Structure

Abstract

The microwave and millimeterwave spectrum of 15N-fluoracetonitrile(C H 2F C 15N) in the ground vibrational state are investigated in the region between 8 and 150 GHz. The measured transitions are fitted to a H amiltonian with three rotational constants, five quartic and seven sextic centrifugal distortion constants in the symmetric top limit of van Eijck-Typke and in the s-reduction of Watson. The rotational constants are used to improve the calculated restructure of the fluoracetonitrile molecule.

“…XIII in [2]). It was derived from the experimental rotational con stants of three isotopomers, H2F 12C12C 14N [3], H2F 12C 12C15N [4], and D2F 12C 12C14N [1], supple mented by our experimental knowledge of the com plete 14N nuclear quadrupole coupling tensor. The latter was used as extra information on the bending angle of the CCN chain.…”
