title: Perfect1JCH-resolved HSQC: Efficient measurement of one-bond proton-carbon coupling constants along the indirect dimension.
abstract: A versatile1JCH-resolved HSQC pulse scheme for the speedy, accurate and automated determination of one-bond proton-carbon coupling constants is reported. The implementation of a perfectBIRD element allows a straightforward measurement from the clean doublets obtained along the highly resolved F1 dimension, even for each individual1JCHaand1JCHbin diastereotopic HaCHbmethylene groups. Real-time homodecoupling during acquisition and other alternatives to minimize accidental signal overlapping in overcrowded spectra are also discussed.
