Fourier transform emission spectroscopy: The B 4Sigma - -X 4Sigma - transition of BC
Abstract
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 Δv=0 vibrational sequence of the B 4Σ-- X 4Σ- transition near 5590 Å was rotationally analyzed. A set of spectroscopic constants were derived for the 0-0, 1-1, 2-2, and 3-3 vibrational bands, including re =1.491 16(34) Å for the X 4Σ- state and re =1.460 23(29) Å for the B 4Σ- state.
