✦ Synopsis

Nz(A. u = O-3) produced by the AI(~P~,~) + N2 reaction and detected by laser-induced fluorescence undergoes rapid, stcpwise vibrational relaxation but slow electronic quenching with added CH4 or CF4. Rate constants, k& of 1.5,3.1, and 5.0 X lo-l2 cm3 s-' are measured for Q = CH4, u = 1-3, and O-47,1.8, and 5.5 X lo-r2 cm3 s-' for Q = CF4, u = l-3, with =+20% accuracy (lo). Information is also obtained for the unrelaxed, relative u populations.
