## Abstract This article gives the experimental results of UV measurements made on a number of benzophenones with ethyl, __iso__propyl and __tert.__butyl groups as substituents. The results are compared with the previously published data on the corresponding methylβsubstituted benzophenones^1,2,3,4
One of the most thoroughly studied photochemical California reactions is the photoreduction of an aromatic ketone in 2-propanol or other secondary alcohol(l).
Ultraviolet irradiation of benzophenone in 2-proPano12 leads to the radicals3'4 (c,H,),&0H I and (cH,&~H II, (C,H,)aC=O\*+ (CHs)aCHOH --i, (C&)&OH + (CHs)ztOH (I)
