The 13 C and 15 N CPMAS NMR spectra of 18 pyrazoles substituted at position 1 by dinitrophenyl and trinitrophenyl (picryl) groups have been recorded. To help in the assignments, some of these compounds were studied in DMSO‐ d 6 solution. Phenomena such as the conformation of the N ‐aryl groups and broadening of splittings due to quadrupolar nuclei are discussed. Copyright © 2008 John Wiley & Sons, Ltd.
