摘要
The accuracy and practicality of measuring heteronuclear scalar coupling constants, (n)J(CH), from modern NMR experimental methods is examined, based on F1 or F2 evolution of (n)J(CH) in HSQMBC (including EXSIDE) and HMBC experiments. The results from these methods are compared to both robust experimental data (derived from coupled C-13 spectra), computed (Density Functional Theory) and literature values where available. We report on the accuracy, ease of use and time efficiency of these multi-dimensional methods and highlight their extent and limitations.
