## Abstract We have calculated the heats of formation (HOFs) for a series of polyazidocubanes by using the density functional theory (DFT), Hartree‐Fock, and MP2 methods with 6‐31G\* basis set as well as semiempirical methods. The cubane skeleton was chosen for a reference compound, that is, the cu
