Online Resources

Informational websites and online tools that are helpful for chemists using NMR

Online Periodic Table. Trying out a new nucleus? Get oriented by reading a little about it here:
http://chem.ch.huji.ac.il/nmr/techniques/1d/multi.html

Online Karplus calculator. Calculates torsion angles based on 1H-1H 3-bond coupling constants, and vice versa:

Chemical shift thermometers. Want to know what your *actual* sample temperature is? Insert either a neat methanol or neat ethylene glycol standard in the magnet, measure the chemical shift difference between the peaks, and use the tools on this page to calculate the temperature:
