Recent experimental results on the thermal decomposition and the reverse recombination of alkyl and haloalkyl peroxynitrates are modelled with an SACM formalism. The molecules RO 2 NO 2 with R = CH 3 , CF 3 , CF 2 Cl, CFCl 2 , CCl 3 , and C 2 H 5 are considered. Detailed and simplified reduced falloff expressions are compared. Limiting low ( o ) and high pressure ( x ) rate constants, such as derived from a fit of these falloff expressions to the experiments, are compared with absolute predictions, based on general knowledge about energy transfer (〈Δ E 〉 in o ) and on a recently proposed simple SACM estimate for x . The analysis also allows for a derivation of the bond energies of the mentioned molecules.
