POTENTIAL ENERGY CURVES FOR N2, NO, O2, AND CORRESPONDING IONS

Potential energy curves for the observed electronic states of N2, N2, NO, NO, O2 and O2 were calculated from published spectroscopic data by a numerical modification of the Rydberg-Klein method. Potential energy curves for a number of predicted but unobserved states of these molecules, and of the ground states of N2- unstable, NO- and O2-, were estimated with the help of simple theoretical considerations, published quantum-mechanical calculations, and indirect experimental evidence. The results are presented graphically.
