4 Evaluation of energy required to change orientation of the nuclear spin within the external magnetic field
WASHINGTON, May 20, 2014 /PRNewswire-USNewswire/ -- In a new paper in The Journal of Chemical Physics, produced by AIP Publishing, a research team in the United Kingdom and the United States describes how water molecules "caged" in fullerene spheres ("buckyballs") are providing a deeper insight into spin isomers -- varieties of a molecule that differ in their nuclear spin.
Part three concerns the use of Mossbauer spectra in studying phenomena related to nuclear spin states and the effects on the structures of compounds.
Additional magnetic field pulses were used to tilt the direction of the nuclear spin and create the superposition states.
Thirty-nine minutes may not seem very long but as it only takes one-hundred-thousandth of a second to flip the nuclear spin of a phosphorus ion -- the type of operation used to run quantum calculations -- in theory over 20 million operations could be applied in the time it takes for the superposition to naturally decay by one percent," said Stephanie Simmons of Oxford University, an author of the paper in the U.
