Notes:
Geminal 15N—13C coupling constants have been measured in a series of 15N-enriched 1-phenyl-3,5-dialkyl-substituted pyrazoles. The importance of the orientation of the nitrogen lone-pair in determining the magnitude of 2J(15N13C) values is reflected in the enhanced coupling observed for those carbon atoms lying close in space to the lone-pair electrons.
