Abstract
Fieser and Fieser1 have recently deduced molecular rotation contributions for the various asymmetric centres in the steroid skeleton. Their values for the contribution of C(17) were obtained, in the absence of data permitting direct comparison, from the molecular rotation of cholestane by subtracting the contributions of all the other asymmetric centres, some of which (those of C(9), C(10) and C(13)) appear to be unreliable.
