Abstract

HF, MP2 and MP4SDTQ (single-point) calculations are performed on structures and energetics of C₃N⁺ isomers. It is shown that electron correlation is very prominent in determining structures, frequencies and energetics of C₃N⁺ isomers, and Schlegel's projected technique has a profound effect on the energetics of C₃N⁺ isomers due to spin contamination for triplet states.
