| 英文摘要 | The near-ultraviolet band system of the jet-cooled boron difluoride free radical has been studied by a combination of laser-induced fluorescence and single vibronic level wavelength resolved emission spectroscopies. The radical was produced in a supersonic discharge jet using a precursor mixture of 1%-3% of BF3 or (BF3)-B-10 in high pressure argon. A large number of bands were found in the 340-286 nm region and assigned as transitions from the (X) over tilde (2)A(1) ground state to the lower RennerTeller component of the (A) over tilde (2)Pi excited state, based on our previous ab initio potential energy surface predictions, matching the emission spectra Franck-Condon profiles of (BF2)-B-11 and (BF2)-B-10, and comparison of observed and calculated boron isotope effects. Several bands have been rotationally analyzed providing ground state structural parameters of r(0)'' (BF) = 1.3102(9) angstrom and theta(0)'' (FBF) = 119.7(6)degrees. The ground state totally symmetric vibrational energy levels of both boron isotopologues have also been measured and assigned up to energies of more than 8000 cm(-1). Although BF2 might be considered to be a "simple" free radical, understanding the details of its electronic spectrum remains a major challenge for both theory and experiment.
