Abstract
The spectral inertness of the ---$NH^{+}_{3}$ group is examined using a substituent potential which has both short and long-range characteristics. The positively charged nitrogen dominates the potential although to obtain a satisfactory description of observed spectral shifts in the electronic spectra of aromatic hydrocarbons account must be taken of the repulsion arising from overlap of substituent and hydrocarbon $\pi$-orbitals. The substituent parameters for the potential are estimated. Using perturbation theory the shifts of bands associated with a rearrangement of charge within the molecule are calculated assuming that only the inductive effect is important. Finally the potential used here is compared to that used by Bishop and Craig.
