%X The proton magnetic resonance spectra of benzofuran, dibenzofuran, indole, 7-azaindole, carbazole, and 4-azacarbazole (&#945;-carboline) have been investigated at 100 Mc/s, and the spectral parameters for these molecules have been obtained. The presence of cross-ring coupling constants involving the NH proton of indole and carbazole is reported.
