Abstract

The ^13^C n.m.r. spectra of the N‐methylated mono‐ and diazanaphthalenes have been recorded and analysed. It has been shown that N‐methylation as well as N‐protonation in cinnoline occur predominantly at the β‐nitrogen atom. N‐methylation and N‐protonation show a similar effect on the ^13^C chemical shifts.

## Abstract The ^13^C chemical shifts of the diazanaphthalenes have been recorded as a function of the pH value, providing classical titration curves. From these curves the p__K__~1~ and p__K__~2~ values have been determined taking into account the activity coefficients. The changes in ^13^C chemic

## Abstract The site of hydration for 1,6‐ and 1,7‐naphthyridine has been determined by specific line broadening in the ^1^H n.m.r. spectra on the addition of water. The site of hydration appears to be the same as the site of protonation (β‐nitrogen atom). The site of hydration in quinazoline has b
