%X The carbon-13 N.M.R. spectra of a series of 6&#946;-substituted-5&#945;- cholestane-3&#946;,5-diols have been determined. The &#947;- and &#948;-shifts associated with those carbons involved in a direct steric interaction with the 6&#946;-substituent, i.e. C4, C8, C10 and C19, are found to be upfield or downfield depending on the nature of the substituent and its geometric relationship to the observed carbon. In particular, the-&#948;- shifts at C19 are increasingly downfield as the size of the substituent is increased.
