  6. Triple-resonance nuclear magnetic resonance spectroscopy

    en.wikipedia.org/wiki/Triple-resonance_nuclear...

    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.

Guaiacol (2-methoxyphenol, O-Methylcatechol) Mequinol (4-Methoxyphenol) Dimethoxybenzenes — can be derived from benzenediols by two rounds of O-methylation. Veratrole (1,2-Dimethoxybenzene) 1,3-Dimethoxybenzene; 1,4-Dimethoxybenzene

  8. Nuclear magnetic resonance database method - Wikipedia

    en.wikipedia.org/wiki/Nuclear_magnetic_resonance...

    Yoshito Kishi's group at Harvard University has reported NMR databases for 1,3,5-triols [1] 1,2,3-triols, 1,2,3,4-tetraols, and 1,2,3,4,5-pentaols. [2] The stereochemistry of any 1,2,3-triol may be determined by comparing it with the database, even if the remainder of the unknown molecule is different from the database template compounds.

  9. Nuclear magnetic resonance spectroscopy - Wikipedia

    A 900 MHz NMR instrument with a 21.1 T magnet at HWB-NMR, Birmingham, UK. Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique based on re-orientation of atomic nuclei with non-zero nuclear spins in an external magnetic field.
