NHIs with R= NO (known as nitroso N‐heterocyclic imines, NNHIs) have special importance
in ozone depletion protection as well as in drug discovery. The electronic structure of these
compounds has not been thoroughly explored. A few experimental studies indicated that the
(NHC)= N bond is weak; a few other studies indicated that the N− N bond is weak in these
species. It is important to establish the chemical bond variations in NNHIs. Density functional …
