Abstract

The collisional widths of ~160 transitions belonging mainly to the 2ν2ν2, 3ν2–2ν2, and 4ν2–3ν2 hot bands of the H216O molecule have been measured on Fourier-transform air–methane flame spectra at 2000 K and analyzed, showing a strong decrease in the collisional widths when the rotational quantum number J increases, as well as a nonnegligible decrease of the collisional widths when the υ2 vibrational quantum number increases.
