We studied the luminescence of molecular nitrogen nanoclusters containing stabilized nitrogen, oxygen, hydrogen, and deuterium atoms. Optical spectra were observed during the destruction of these ensembles of nanoclusters accompanied by a rapid release of chemical energy stored in the samples. Several interesting features were observed including a broad band near lambda approximate to 360 nm, which was identified as emission corresponding to 2A(g) -> 1A(g) transition of N-4(D-2h) polymeric nitrogen. Also the sharp lines at lambda similar to 336 and 473 nm were observed, and their assignments to ND radicals are discussed.
