Some complementary techniques that have been used recently to study the decomposition of solid nitramines include FTIR spectroscopy of the vapor above a rapidly heated film or vapor trapped by rapid cooling (Brill, T.

9. In α-HNIW one NNCN torsional angle is 4° from anti-periplanar; the others deviate by more than 47°. In β-HNIW two NNCN torsional angles are less than 3° from anti-periplanar; the others deviate by more than 54°. Results of X-ray structure determinations were kindly supplied by Dr. Richard Gilardi, Naval Research Laboratory, Washington, DC.
