Three Dimensional NMR Spectroscopy
A three dimensional NMR experiment (see picture above) can easily be constructed from a two dimensional one by inserting an additional indirect evolution time and a second mixing period between the first mixing period and the direct data acqusition.
3D-Nuclear Magnetic Resonance - an overview - ScienceDirect
A 3D NMR experiment is similar to a 2D experiment in that it consists of a series of pulses and delays during which the magnetization evolves under the influence of the chemical shifts and coupling constants or is transferred via nuclear Overhauser effects. You might find these chapters and articles relevant to this topic.
Triple-resonance nuclear magnetic resonance spectroscopy
Triple resonance experiments are a set of multi-dimensional nuclear magnetic resonance spectroscopy (NMR) experiments that link three types of atomic nuclei, most typically consisting of 1 H, 15 N and 13 C. These experiments are often used to assign specific resonance signals to specific atoms in an isotopically-enriched protein.
3D NMR Spectra - an overview | ScienceDirect Topics
'3D NMR Spectra' refers to a type of spectroscopy where a third time axis is introduced, allowing visualization of contour peaks in a cube defined by three axes derived from Fourier transformation steps. It is used for protein structure determination and investigating the structures of macromolecules like proteins and synthetic polymers.

6.2: Heteronuclear 3D NMR- Resonance Assignment in Proteins
2023年8月10日 · In this Chapter we will show how the well-resolved 2D 15 N-HSQC resonances can be assigned to specific residues and chemical groups within protein samples. As an example, we will consider a couple of complementary types of 3D NMR data: HNCACB and CBCA (CO)NH and their joint application for making heteronuclear NMR resonance assignment in proteins.
