摘要: The 2 A 1 ground state of NO2 and the so‐called 2 B 2 excited state are shown to form a strongly coupled pair of 2 A′ states when asymmetric distortion is considered. This coupling is of the Jahn–Teller type although the degeneracy between the states is accidental and the normal coordinates are not equivalent.
