Microwave Spectrum and Molecular Structure of Bromine Trifluoride

Abstract

The moments of inertia and quadrupole coupling coefficients of both Br79F3 and Br81F3 were determined from a number of microwave transitions. From the moments of inertia the bromine trifluoride molecule was found to have a planar distorted — T structure with one short, 1.721 A, and two long, 1.810 A Br–F bonds. The FBrF′ angle was found to be 86° 12.6′.
