Contrary to a widely held view , it is possible to distinguish by UV spectroscopy betwwen methyl‐substituted 2,4‐cyclohexadienones of the type showln. A notable relationship exists between the UV maximum of the relatively intense π * ,π region and the number and position of additional methyl groups.
