Three N ‐substituted pyrazoles and three N ‐substituted indazoles [1‐(4‐nitrophenyl)‐3,5‐dimethylpyrazole (1), 1‐(2,4‐dinitrophenyl)‐3,5‐dimethylpyrazole (2), 1‐tosyl‐pyrazole (3), 1‐ p ‐chlorobenzoylindazole (4), 1‐tosylinda‐zole (5) and 2‐(2‐hydroxy‐2‐phenylethyl)‐indazole (6)] have been studied by NMR spectroscopy in solution ( 1 H, 13 C, 15 N) and in the solid state ( 13 C, 15 N). The chemical shifts have been compared with GIAO/DFT calculated absolute shieldings. Some discrepancies have been analyzed. Copyright © 2006 John Wiley & Sons, Ltd.
