摘要：

Ab initio calculations on the singlet-triplet energy separation of dimetylcarbene are reported. Correlation methods based on a single determinant reference function as well as the multiconfigurational approach are used in combination with various basis sets. Our best calculation predicts, inaccord with recent experiments, a singlet-triplet splitting of 1.64 kcal/mol in favor of the singlet state of dimethylcarbene.
