Need for high resolution 2D spectra

July 28, 2020 Experimental Possibilities, Nuclear Magnetic Resonance (NMR) 0

¹³C NMR spectra provide wide range chemical shift, and it suggests that can easily distinguish each signals. But carbon resolution of 2D spectra such as HSQC and HMBC is worse than 1D ¹³C spectra due to small data points. In order to analyze a compound with close ¹³C chemical shifts, a high resolution 2D spectrum is required frequently. In this document, some improvements to distinguish each signals on ¹³C axis of 2D hetero nuclear experiments are presented.
