## 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 fro
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
## Abstract A simple and sensitive method has been developed using preconcentration technique solid phase microextraction (SPME) and analytical technique HPLC‐UV for the determination of octahydro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine (HMX) and hexahydro‐1,3,5‐trinitro‐1,3,5‐triazine (RDX) from th
