Nitramines classification

Sensitivity Very low (requires nitramine explosive for initiation) Classification Secondary explosive... 

Our own experience is confined to polynitramines of various types (ten in all) which follow the above classification and show the NO2 absorptions in the ranges 1587—1530 cm and 1292—1260 cm . This is presumably the region of absorption for nitramines generally, except for the cases of nitroguanidines, and ureas in which alternative prototropic forms are possible which might absorb at higher frequencies. 

According to the common classification [2], explosives containing nitro groups may be divided as (1) nitroaromatic compounds, which contain a C-NO2 bond (where the carbon atom is part of an aromatic system) (2) nitrate esters, which contain a C-O-NO2 bond and (3) nitramines, which contain a C-N-N02bond.
