## Abstract Various methods of preparation of the different polymorphs of HMX have been evaluated. Infrared and Raman spectra have been used to differentiate the polymorphs and understand their conformational behaviour. Possible conformation of the ฮณ form has been suggested.

## Abstract A new series of relatively stable adducts of octahydroโ1,3,5,7โtetranitroโ1,3,5,7โtetrazocine (HMX) with derivatives of pyridineโNโoxide were prepared. In addition, relative stable new adducts of HMX were prepared with 5โmembered, 6โmembered, and condensedโring heterocyclic compounds. M
The \({ }^{14} \mathrm{C}\)-uniformly labeled (UL) explosive, octahydro-1,3,5,7-tetranitro-1,3,5,7tetrazocine (HMX) was synthesized in \(40 \%\) yield by nitrolysis of \({ }^{14} \mathrm{C}\)-labeled hexamethylenetetramine (hexamine) in the presence of boron trifluoride diethyl etherate as catalyst.
