Molecular orbital interpretation of the ultra-violet spectra of nitroguanidine and related nitramines
Abstract
The ultra-violet absorption spectra of nitroguanidine is tentatively assigned on the basis of a VESCF CI MO calculation of its singlet excited states. Its absorption envelope is attributed to σ, π, and “lone-pair” electron transitions. The application of the results to other conjugated nitramines is discussed and the spectra of conjugated and unconjugated nitramines are compared.
