Abstract

Generalized valence bond (GVB) calculations are reported for the ³B₁, ¹A₁, and ¹B₁ states of the CH₂ molecule. The GVB method is discussed and compared with other multi-configuration and separated pair methods. The lowest singlet state (¹A₁) is found to lie 0.50 eV about the lowest triplet state (³B₁) and the ¹B₁-¹A₁ separation is found to be 1.40 eV.
