In 2008, Varian bought Oxford Diffraction, a British company specializing in X-ray diffraction equipment. On 27 July 2009, Agilent Technologies announced it would buy Varian Inc, for $1.5 Billion. On 14 October 2014, Agilent made the strategic decision to close its NMR business. Agilent entered the NMR business in 2010, with the acquisition of ...
Russell gained patents for technology related to nuclear magnetic resonance (NMR), [23] [24] [25] as used in magnetic resonance imaging (MRI), thermionic tubes, and various radar technologies. [3] [15] Sigurd's inventions, some of which he patented, included a system of pumps, filters, and heaters for his swimming pool, as well as a high-speed ...
Varian Associates was one of the first high-tech companies in Silicon Valley.It was founded in 1948 by Russell H. and Sigurd F. Varian, William Webster Hansen, and Edward Ginzton to sell the klystron, the first vacuum tube which could amplify electromagnetic waves at microwave frequencies, and other electromagnetic equipment.

Surface nuclear magnetic resonance (SNMR), also known as magnetic resonance Sounding (MRS), is a geophysical technique specially designed for hydrogeology.It is based on the principle of nuclear magnetic resonance (NMR) and measurements can be used to indirectly estimate the water content of saturated and unsaturated zones in the earth's subsurface.

NMR is extensively used in medicine in the form of magnetic resonance imaging. NMR is widely used in organic chemistry and industrially mainly for analysis of chemicals. The technique is also used to measure the ratio between water and fat in foods, monitor the flow of corrosive fluids in pipes, or to study molecular structures such as ...

The difference between the chemical shift of a given nucleus in a diamagnetic vs. a paramagnetic environment is called the hyperfine shift.In solution the isotropic hyperfine chemical shift for nickelocene is −255 ppm, which is the difference between the observed shift (ca. −260 ppm) and the shift observed for a diamagnetic analogue ferrocene (ca. 5 ppm).
