✦ Synopsis

Time-resolved optica! interferometry of the relaxation region aftet the primary shock u~lve in a free-piston shock tube is used to measure the dissociation rate of nitrogen by N2 and N without inert gas dilution. The results cover a temperature range of 6000 -14000% and give for N2 + N2 -Ni-N+N2, kdl=2.3 x i02' +-'-' T-3o5 exe<-113200/T), for Nz + N -N + N + N , k& = 8.5 x 10z5 * o-Z T-'*' exp (--113200/T) (cm3 mole-' set-') thus confiuming the strong temperature dependence of the pre-exponential factor reported by Hanson and Baganoff.

## Abstract The three‐body dissociation of 1,3,5‐triazine (s‐triazine, s‐C~3~H~3~N~3~ → 3HCN) has been observed in incident shock waves with the laser‐schlieren technique. The experiments use 5% triazine/Kr and cover 1630–2350 K for 100–600 Torr. These experiments show dissociation rates with stron
