| Abstract: | | 1. |
Study has been made of the circular dichroism spectra of 20-ketosteroids containing a three-membered ring (methylene, epoxide, episulfide, or aziridine) in the  -position with respect to the keto group.
| | 2. |
The observed n  * and * transition Cotton effects have been correlated with the preferred conformation of the molecule.
