✦ Synopsis
In order to investigate the influence of electron correlation on the characteristic N-N bond in connection with the impact sensitivity in nitramines, only the N-NO2 bond length of N,Ndimethylnitramine is optimized by the ab initio molecular orbital method to assess the effect of the electron correlation on the N-NO* bond lengths. It is found that a considerable lengthening of the N-NO2 bond appears compared with N-NH1 and C-C bonds. This lengthening of the N-NO* bond is ascribed to the antibonding character of the N-NO2 bond in the LUMO.
