unusual facts about Fluorine-19 NMR


Phosphorus pentafluoride

Fluorine-19 NMR spectroscopy, even at temperatures as low as −100 °C, fails to distinguish the axial from the equatorial fluorine environments.


E1cB-elimination reaction

Fluorine kinetic isotope effects are also applied in the labeling of Radiopharmaceuticals and other compounds in medical research.

Energy applications of nanotechnology

In a study concerning ultracapacitors or supercapacitors, researchers at the Sungkyunkwan University in the Republic of Korea explored the possibility of increasing the capacitance of electrodes through the addition of fluorine atoms to the walls of carbon nanotubes.

Jadarite

Jadarite's chemical formula is very close to the formula ("sodium lithium boron silicate hydroxide with fluorine") invented for the fictional substance kryptonite in the 2006 film Superman Returns.

Jerome Karle

As part of a plan to accumulate enough money to pay for further graduate studies, Karle took a position in Albany, New York with the New York State Department of Health, where he developed a method to measure dissolved fluorine levels, a technique that would become a standard for water fluoridation.

NMR spectroscopy of stereoisomers

Mosher's acid contains a -CF3 group, so if the adduct has no other fluorine atoms, the 19F NMR of a racemic mixture shows just two peaks, one for each stereoisomer.

Pamur

Local ground water in the area contains fluorine, and due to this contamination, consumption of the ground water causes fluorosis, a potentially debilitating disease affecting bones and joints.

Thermobaric weapon

The AGM-114N Hellfire II, first used by U.S. forces in 2003 in Iraq, uses a Metal Augmented Charge (MAC) warhead that contains a thermobaric explosive fill using fluoridated aluminium layered between the charge casing and a PBXN-112 explosive mixture.
