(209Bi) Bismuth NMR

Use our NMR service that provides 209Bi NMR and many other NMR techniques.

Bismuth (Bi) has one high sensitivity NMR active nucleus, 209Bi (fig. 1). It is quadrupolar and yields very broad signals even in the most symmetric of environments over a very wide chemical shift range. Only Bi3+ and [BiF6]- have been observed by high resolution NMR so chemical shift information (fig. 2) is very limited.

Safety note

Some of the materials mentioned here are very dangerous. Ask a qualified chemist for advice before handling them. Qualified chemists should check the relevant safety literature before handling or giving advice about unfamiliar substances. NMR solvents are toxic and most are flammable. Specifically, bismuth salts are toxic in large quantities besides any toxicity arising from the anion. 209Bi is very slightly radioactive but not to an extent that it can be dangerous.
