Abstract
Vibrationally‐excited ground state O2 is detected in a CH4/O2 flame in levels v‘=9–11 by laser‐induced fluorescence in the B 3Σ−u–X 3Σ−g Schumann–Runge system. Accurate line positions are measured by calibration against OH(A–X) lines appearing in the same spectra. Signal levels indicate that measurements up to at least v‘=18 should be practical in such flames. The absolute energies of the three vibrational levels agree very well with RKR calculations of Albritton, based on earlier experimental work, but there is substantial disagreement for v‘=11 with the extensive data of Creek and Nicholls.Keywords
