## Abstract A theoretical and NMR‐spectroscopic conformational analysis is presented of the 3‐methyl‐1,3,5‐hexatrienes and of (__Z__)‐3‐__tert__‐butyl‐1,3,5‐hexatriene. It is shown that (__E__)‐3‐methyl‐1,3,5‐hexatriene exists mainly as the __tEt__ rotamer and (__Z__)‐3‐methyl‐1,3,5‐hexatriene as t

A two-dimensional potential-energy surface was calculated for the ground state of Z-1,3,5-hexatriene in order to study the conformational relaxation after its photochemical formation from 1,3-cyclohexadiene. The potential-energy surface was scanned along both C-C single bond torsional angles while a
triplet-triplet absorption spectra, quantum efficiencies of intersystem crossin g, triplet extinction coefficients, and triplet energy levels of 1,6diphenyl-1,3,5hexatriene, and 1,GliphenyL1,3,5,7-octatetraene, in ethanol and benzene have been obtained. l%e quantum efficiencies of intersystem crossi
