摘要：

The collisional widths of approximately 160 transitions belonging mainly to the 2-nu(2)-nu(2), 3-nu(2)-2-nu(2), and 4-nu(2)-3-nu(2) hot bands of the (H2O)-O-16 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 upsilon(2) vibrational quantum number increases.
