✦ Synopsis

Spectra of CH 4 / O 2 low-pressure flames have been recorded at a resolution of 0.020 cm 01 with an infrared Fourier transform spectrometer in the spectral range 1790 to 5029 cm 01 . Through the use of CO 2 and CO emission lines, the flame temperature has been determined with a precision of the order of 1%. Results (wavenumbers, band centers, and spectroscopic constants) concerning six new vibrational transitions D£ 3 Å 1 with (2£ 1 / £ 2 ) Å 5 which have not been observed earlier and which occur between highly excited vibrational states are reported.
