Abstract: he isomerization and thermal elimination of dinitrodiazophenol (DDNP)were investigated by using the AM1 method.The resuIts showed that the quinoid isomer is more stable than cyclic isomer; the activation energy of the isomerization(quinoid isomer→cyclic isomer)is 181.506 kJ/mol; the activation energies of eliminating NO2on atom C(6)and C(4) of quinoid isomer are 120.361 kJ/mol and 130.273 kJ/mol,respectively; and those ofcyclic isomers are 131. 808 and 122. 708 kJ/mol,respectively.

Key words: Dinitrodiazophenol, Isomerization, Thermal elimination, Transition state
