Abstract
The preparation of pure octahydro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine (HMX) labelled with nitrogen‐15 and deuterium was accomplished by sequential nitrolysis of appropriately labelled octahydro‐1,5‐diacetyl‐3,7‐endomethylene‐1,3,5,7‐tetrazocine. The latter compounds were obtained from the reaction of acetic anhydride with hexamethylenetetramine that was specifically labelled by the reaction of the appropriate formaldehyde and ammonia.

## Abstract Procedures are described for the synthesis of 1,3,5‐trinitro‐1,3,5‐triazacyclohexane (RDX), 1,3,5,7‐tetranitro‐1,3,5,7‐tetraazacyclooctane (HMX) fully labeled with nitrogen‐15.
The structures of aand b-HMX were fully optimized and the vibrational frequencies computed at the hybrid DFT B3LYP/6-31G(d, p) level of theory. The DCI mass spectrum of HMX using ammonia (NH 3 ) as a ™soft∫ ionising gas is reported. Field desorption mass spectrometry (FD) was used because of the hig
