The temperature dependence of the 13 C chemical shifts in tristearin and methyl stearate has been investigated in both the melt and solution phases. Intramolecular conformational changes dominate the observed behaviour and there is little evidence for intermolecular interactions even in the melt pha

## Abstract Carbonβ13 chemical shift parameters for equatorial and axial substituents in cyclohexane are reported for methyl, ethyl, isopropyl, methoxy and phthalimido substituents. The usefulness of the alkyl parameters is demonstrated by the agreement between calculated and observed ^13^C shifts
## Abstract The ^13^C chemical shifts for 1,3βdithiane and 9 methyl substituted derivatives are reported. Only three of the methylβ1,3βdithianes were conformationally anancomeric and hence the conformational equilibria must be taken into account when deriving the values of the different substituent
