2022年9月19日 · Triple resonance experiments (3D) are a set of multi-dimensional nuclear magnetic resonance spectroscopy (NMR) experiments that link three types of atomic nuclei, 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.

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.

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.

'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.

发展三维核磁共振技术（3d-nmr） ：随着nmr谱在生物大分子结构分析中的应用，nmr技术所提供的结构信息的数量和复杂性呈几何级数增加。对三维空间的构象和大分子与小分子（或小分析与小分子）之间的相互作用等，二维核磁共振(2d-nmr)已显得无能为力了，因此 ...

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.

2023年2月2日 · In this comprehensive guide, we will delve deeply into the principles, methodologies, and applications of 2D and 3D NMR spectroscopy, equipping you with a robust understanding of these advanced techniques.

Conceptually, 3D-NMR spectroscopy is a straightforward extension of the 2D acquisition strategy and generally combines two existing 2D-NMR experiments (Griesinger et al. 1989), as shown in Fig. 6a. For example, a 3D experiment may start with a first NOESY scheme, but the detection pulse is replaced by a further HSQC experiment.
