摘要：

The gas-phase emission spectrum of BC was recorded using a high resolution Fourier transform spectrometer. The BC radical was produced by sputtering in a composite-wall hollow cathode discharge lamp. The DELTA-nu = 0 vibrational sequence of the B4-SIGMA- -X4-SIGMA- transition near 5590 angstrom was rotationally analyzed. A set of spectroscopic constants were derived for the 0-0, 1-1, 2-2, and 3-3 vibrational bands, including r(e) = 1.491 16(34) angstrom for the X4-SIGMA-(-) state and r(e) = 1.460 23(29) angstrom for the B4-SIGMA-(-) state.
