Direct and long-range 1HΓ15N correlations for cryptolepinone and its N5-oxide as a mixture in were determined using a combination of 1HΓ15N GHSQC and GHMBC experiments. The 15N chemi-DMSO-d 6 cal shifts of cryptolepinone in the mixture were comparable to those reported previously for a pure sample o
## Abstract The ^15^N chemical shifts of thirteen NHβpyrazoles in the solid state and of seven NHβpyrazoles in [^2^H~8~] THF solution at 170β175 K (with frozen annular tautomerism) are reported. The solidβstate values are discussed using an additive model. The differences in chemical shifts between
