## Abstract The temperature dependence of the carbon‐13 NMR signals in three completely substituted 1,3,5‐trineopentylbenzenes has been studied by the Fourier transform technique. The assignment of all peaks was based on studies of 1,3,5‐trineopentylbenzene and some of its mono‐ and disubstituted d
