Abstract:
The rotational spectrum of an asymmetrically substituted isotopologue of the fluoroformyloxyl radical FC(16)O(18)O(•) with resolved fine and hyperfine structures were measured and analyzed for the very first time. The molecular parameters of this radical obtained from the spectral analysis were processed along with the symmetrical isotopologues FC(16)O2(•) and FC(18)O2(•) and accurate substitution geometry was attained. In addition to those, coupled cluster quantum chemistry calculations were used to scale the experimental parameters, and in this manner, trustworthy values of the equilibrium and ground state geometries were derived.

Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...
