Abstract

Chloro‐, methoxy‐ and methyl‐substituents in the 4‐position of phenanthrenes exert a profound and diagnostic influence on the ^1^H chemicalshift of H‐5, and from ^13^C measurements it is considered to be dueto an anisotropic effect.

## Abstract The ^1^H chemical shifts of 124 compounds containing a variety of functional groups have been recorded in CDCl~3~ and DMSO‐__d__~6~ (henceforth DMSO) solvents. The ^1^H solvent shift Δδ = δ(DMSO) − δ(CDCl~3~) varies from −0.3 to +4.6 ppm. This solvent shift can be accurately predicted (

## Abstract The complex character of the temperature dependence of the ^1^H NMR chemical shifts of indenyl‐lithium and ‐sodium in dimethoxyethane is explained. It is shown that the cation causes a polarisation of the CH bonds and thus influences the proton shifts of the anion, both directly by its
