Abstract

This paper reports 261 substituent increments for the ^1^HNMR. chemical shifts (solvent: CDCl~3~) of the 18‐ and 19‐methyl protons of 9β, 10α(retro)‐steroids relative to 5β,9β,10α,‐androstane. The increments were calculated by a least‐squares procedure from 1334 spectra of 759 different steroids.

## Abstract In Part II of this series we report 292 substituent increments for the ^1^H‐NMR. chemical shifts (solvent: CDCl~3~) of the 18‐ and 19‐methyl protons of 9α,10β(normal)‐steroids relative to 5α,9α,10β,‐androstane. The increments were calculated by a least‐squares procedure from 988 spectra
