    density of states and detonation properties of trans and cis configurations of azocubane. All properties have been obtained using the B3LYP functional and 6-31G(d‚p) basis set. Also‚ IR‚ UV-Vis‚ CD and NMR spectra of the structures were simulated. The volumes of the structures computed to get the densities of the molecules. All calculations carried out in gas phase at temperature 293.15 k and pressure 1 atm. The simulation results revealed that the trans configuration of azocubane exhibits more stability
