Abstract: The influence of substituents on wavenumbers, integrated absorption intensities, and half-band widths of the v_as(NNN) bands of nine substituted phenyl azides has been discussed. A linear relationship between integrated absorption intensities (log A) and Hammett σ  and σ⁺ substituent constants of electron-withdrawing substituents has been observed (ρ = 0.201 and ρ⁺ = 0.201, respectively). It has been found that the azide group is of dual electron nature.
