## Abstract Mesomeric heteropentalene betaines are conjugated fused polyheterocyclic structures that represent interesting intermediates for organic synthesis. Five such structures, containing at least four nitrogen atoms and various substituents, have been characterized by ^1^H, ^13^C and ^15^N NM
## REFERENCE DATA carbons, for various substituent groups and positions were carried out by gated decoupling with NOE. ## RESULTS AND DISCUSSION The I3C NMR chemical shifts of the compounds are shown in Tables 123; 'J(CH) and long-range coupling constants of 2, 9, 13 and 18, measured by gated d
## Abstract ^1^H NMR assignment, including the values of δ~H~ and __J__(H,H) for the cyclopropane moiety, and ^13^C NMR and ^15^N NMR spectral data for ciprofloxacin are presented. Copyright © 2004 John Wiley & Sons, Ltd.
## Abstract ^13^C and ^15^N NMR chemical shifts were measured for __N__^1^‐alkyl‐__N__^2^‐arylthioureas. The absence of decoalescence of the __N__^1^‐alkyl group carbon signals down to 190 K, the europium‐induced chemical shifts and the molecular mechanics calculations indicate that the preferred c
## Abstract ^15^N‐enriched dihydroxamic acids (HONHCO(CH~2~)~__n__~CONHOH, __n__ = 0, 1, and 2) were prepared and their spectra NMR (^1^H, ^13^C, ^15^N) recorded in dimethyl sulfoxide (DMSO) solutions with the aim of determining ^15^N coupling constants (^15^N^1^H and ^15^N^13^C). The results sup
