As a consequence of aggregate formation, no 'H NMR spectra of the amphiphilic antibiotic moenomycin A have been obtained previously. It was now found that the system moenomycin A-D20-C,D, after sonification yielded highly resolved 'H NMR spectra, probably due to the formation of a microemulsion. Sim

## Abstract Unresolvable long range spin‐spin coupling which is not explicitly taken into account in total NMR bandshape analysis is demonstrated to be a potentially important source of systematic error, leading to Ξ”__H__^β‰ ^ and Ξ΄__S__^β‰ ^ values incorrect by __c__. 1 kcal/mol and 2 to 4 cal/(mol K)
