Miscellaneous Physical Properties

The vibrational structure and polarization properties of the phosphorescence spectra of testosterone and two other 4-en-3-ones indicate that excitation to the lowest triplet state causes little change in geometry/ contrary to earlier 

The phase transitions of cholesteryl nonanoate have been studied with a new apparatus for thermal analytical microscopy. The enantiomer ratio of some chiral sulphoxides can be changed from racemic to a modest preference for one enantiomeric form by dissolution in a cholesteryl ester in its liquid-crystalline ( cholesteric ) state. 5,6-Epoxycholestan-3-yl p-nitrobenzoates exhibit liquid-crystal properties, but 5,6-diols and dibromides are inactive.  

Differential pulse polarography has been used for the estimation of progesterone, testosterone, and related 4-en-3-ones in some parenteral formulations (in oil or aqueous suspensions).
