Abstract: The intensity of the long-wavelength UV transition of tocopherols is investigated using the interaction vector model. Intensity of alpha -tocopherol is the lowest of the series because it is the molecule which allows the most efficiently the effects of the alkyl groups to oppose the effects on intensity of the two alkoxy-like groups (a hydroxy group and a fused trimethyleneoxy moiety). Intensity of eta -tocopherol is the highest because the only methyl substituent cannot attenuate the effects of the alkoxy-like groups.
