The millimeter and submillimeter-wave spectrum of boron monofluoride: Equilibrium structure
Abstract
Utilizing a dc discharge absorption cell the millimeter and submillimeter-wave spectra of 11BF and 10BF have been observed in the v = 0, 1, 2 and v = 0, 1 vibrational states, respectively. The Dunham constants of the two isotopomers and the boron electric nuclear quadrupole coupling constant as well as the spin-rotation interaction constant of boron and fluorine have been determined. By removing from the Y01 Dunham constant the contributions due to the breakdown of the Born-Oppenheimer approximation, the resulting equilibrium bond distance is r e = 1.262672(7) Å.
