Notes:
It is shown that for phenyl-azo-azulenes substituted in the benzene nucleus (1)the position ṼB.I of the band corresponding to the long-wave transition depends linearly on the Hammett σx value of the substituent X(2)the shift ΔṼB.II of the intense π→π* transition at 24 000 cm-1 on protonation of the azo link depends linearly on σx, provided that σx - σ′x is negative.
