Some Multinuclear NMR Solution and Solid State Studies on 1,8-Bis(dimethylamino)naphthalene and Its Complex with Tetrazole

13C and 15N NMR spectra are measured for 1,8-bis(dimethylamino)naphthalene and its complex with tetrazole in both solution and the solid state. On the basis of the solution and solid state 15N results, an equilibrium involving the half protonated form of the base in the solution of the complex salt was identified. On the other hand, it is found that the 13C results for the solutions are closely similar to those found for the solid state, and are rather insensitive to salt formation.
