Abstract
The invariance of the configuration interaction (CI) energy with respe ct to orbital rotation is considered. The inclusion of all spin coupli ngs versus only those from the first-order interacting space is consid ered. A definition for the analog of a second-order CI calculation whe n inactive electrons are present is proposed.
