Die diamagnetische Anisotropie der CC‐Einfachbindung. Eine Abschätzung auf Grund der Protonenresonanzspektren von 5α‐ und 5β‐Androstan

Abstract

Based on the proton NMR spectra and the known geometry of rings A and B of 5α‐ and 5β‐androstane an equation has been derived for , the anisotropy of the molar diamagnetic susceptibility of the CC single bond, that is equation image where Δ is the analogous quantity for the CH bond. Assuming values between the range for Δ becomes .
