摘要：
Infrared emission from highly vibrationally excited NO2, prepared by collision induced internal conversion, can be detected with 1 cm(-1) spectral and 0.5 mu s time resolution over the 800-10 000 cm(-1) range by time-resolved Fourier transform emission spectroscopy. The energy distribution of vibrationally excited NO2 during collisional deactivation can be extracted from the emission spectra and shows that the energy loss per collision increases dramatically from <50 cm(-1) below 13 000 cm(-1) energy to 1300 cm(-1) at 20 000 cm(-1) energy.
