摘要: With photolysis-probe technique, we have studied vibrational and rotational energy transfers of CH involving the B Σ−2 (v=1, 0⩽N⩽6, F) state by collisions with Ar, CO, N2O. For transfer (VET) measurements, time-resolved fluorescence B-X(0,0) band is monitored following (1,0) excitation. (RET) laser-induced initially populated dispersed using a step-scan Fourier transform spectrometer. The spectra obtained in nanosecond regime may yield RET information under single pressure collider. rate constants intramolecular are evaluated simulation kinetic models. VET lies range 4×10−12to4×10−11cm3molecule−1s−1, efficiency order Ar
