## Abstract A study of several linear and branched alkanes indicates that the temperature dependence of ^13^C chemical shifts is a complex phenomenon in which several nonβadditive effects may be operative. The chemical shift temperature coefficients dΞ΄/d__T__ do, however, reveal some systematic tre

## Abstract The temperature dependence of the chemical shifts of ten commonly employed ^1^H n.m.r. reference compounds of interest to both organic and biological workers was determined using the temperature independent standard ethane at low density. The water soluble standards sodium 2,2βdimethylβ
