## Abstract Two‐dimensional ^1^H‐detected {^1^H, ^13^C} shift correlation spectra of oligosaccharides usually suffer from low resolution in the ^13^C frequency domain. This drawback can be overcome through a simple modification of the HSQC experiment, namely by implementing a selective ^13^C 180° p

A method for spatially three-dimensional (3D) localized twodimensional (2D) 1 H-13 C correlation spectroscopy, localized HSQC, is proposed. This method has the following special feature in the preparation period. The 180°( 13 C) and 180°( 1 H) pulses are separated in time, and the 180°( 13 C) pulse
## Abstract A 3D ^1^H–^13^C–^1^H refocused INEPT transfer experiment is proposed in which the initial coherence transfer of ^1^H longitudinal to ^13^C transverse magnetization is tuned to the long‐range ^1^H, ^13^C couplings while the reverse INEPT component transfers the magnetization to the direc
