摘要: Ab initio calculations are used to characterize the ground and low lying excited electronic states of several linear cyclic isomers cyanogen. In particular, consider excitation energies for selected singlet triplet Σ cyanogen (NCCN), isocyanogen (CNCN), di-isocyanogen (CNNC), diaza-dicarbon (NNCC), corresponding three isomers, including many predictions that presented here first time. Our structures agree well with available experimental data, thereby providing a benchmark assessing other such as isomers. The present also identify possible emitting species some unexplained bands in emission observed from certain temperature matrices. Since, emitter could not be assigned any molecule must responsible
