Notes:
The validity of the rule of repartition of the auxochromes is examined for some symmetric tetramethoxy-azobenzenes, dimethoxy-azobenzenes, and dimethoxy-4′-nitro-azobenzenes whose methoxy groups are in 2,4-, 3,4- and 2,5-position. The rule is confirmed with 2,4-and 2,5-derivatives. The long wave lengths absorption maxima of 3,4,3′,4′-tetramethoxy-azobenzene and of 3,4-dimethoxy-4′-nitro-azobenzene are situated at shorter wave lengths than expected.
