Optical rotatory dispersion of steroids with various chromophores

Conclusions

1. On the basis of a comparative study of the ORD of steroids containing as chromophores the groups C=O, >C=C−C=C< and C=C, it has been established that in all the compounds the ORD is anomalous in the UV region of the spectrum.

2. In steroid compounds the magnitude of the optical rotation increases with an increase in the geometrical dimensions of the chromophoric group.

3. The ORD curves of steroid compounds with various π-electronic chromophores are highly specific and can be used to study their structure and for identification purposes.
