Easy measurement of one-bond proton-carbon and geminal proton-proton coupling constants in diastereotopic methylene groups

Straightforward measurement of individual 1J(CH) and 2J(HH) in diastereotopic CH2 groups” by Josep Saurí, Laura CastañarPau Nolis, Albert Virgili and Teodor ParellaJournal of Magnetic Resonance 242 (2014) 33–40DOI: 10.1016/j.jmr.2014.02.003

The C-HA cross-peak corresponding to a diastereotopic CHAHB methylene spin system exhibits a characteristic 1:0:1 multiplet pattern along the indirect dimension of a ω1-coupled HSQC spectrum.
