Abstract : The explosive RDX exhibits EPR signals when heated to temperatures ranging from 120 C to 200 C. Neat RDX samples give intense EPR signals at 197 C. RDX dissolved into sulfolane gives intense EPR signals at 170 C and weaker signals detected as low as 120 C. A 0.1M solution of RDX in sulfolane gives an EPR spectrum at 170 C which is attributed to a nitroxide radical (H2C(NN02)2(CH2)2N-0). A 1M solution of RDX in sulfolane at 170 C and a neat sample of RDX at 197C give an identical spectrum of a second radical.
