โฆ Synopsis
Diffcrential cross sections of thc process Na*(3 *P) + M(u = 0) Na(3S) + M(u') have been mcasured for several molecules: Hz, D2, Nz, 02, CO, COz, NzO, Cz H4. WC observe two different types of enerpy spectra. One of them displays il typicalIy non-resonant elcctronic to vibrational energy transfer accompanied by a distinct maximum, the other one 3 neur resonant behaviour.
