NMR (nuclear magnetic resonance) is a very powerful tool for identifying compounds. The nucleus of some atoms has nuclear spin (e.g. 1H, 13C, 19F, 31P), although many atoms do not have any nuclear spin (e.g. 12C). A nucleus with spin generates a small magnetic field.
Online Spectral Database: Quick access to millions of NMR, IR, Raman, UV-Vis, and Mass Spectra.*. Search a compound by name, InChI, InChIKey, CAS Registry Number, or Draw a Structure. *Access is currently limited to 10 searches every 30 days.
14 Φεβ 2020 · It describes Nuclear Magnetic Resonance (NMR) in details relevant to Organic Chemistry. It also includes NMR summary data on coupling constants and chemical shift of 1H, 13C, 19F, 31P, 77Se, 11B. Spectra (PDF form) of more than 600 compounds are also provided.
The following exercises are designed to help you become familiar with predicting the 1H NMR spectra of simple organic molecules. For each example you should find the number of signals you expect, where they should show on the scale (chemical shift), and what shape they should be (splitting patterns).
nmrshiftdb2 is a NMR database (web database) for organic structures and their nuclear magnetic resonance (nmr) spectra. It allows for spectrum prediction ( 13 C, 1 H and other nuclei) as well as for searching spectra, structures and other properties.
