 Carbon-13 enriched trifluoroacetic acid David Naugler wrote Sorry for the error in logic. Doubly enriched 13C TFA would only have a relative abundance of 10^-4. We would be happy to achieve single enrichment TFA, F.W. 115. That would give 50% enrichment in the 2 position but a 50X improvement in signal intensity in carbon/fluorine HSQC. Any helpful comments and ideas would be greatly appreciated. dgn -- Paul J.
