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 ...
It is produced by Varian, Inc. The software runs on SPARC machines with Solaris. It is composed of a command line interpreter window, an output window, and a status window. The successor of vnmr is called vnmrJ.
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.
The Russell Varian Prize was an international scientific prize awarded for a single, high-impact and innovative contribution in the field of nuclear magnetic resonance (NMR), that laid the foundation for the development of new technologies in the field. [1]
Nuclear magnetic resonance (NMR) spectroscopy uses the intrinsic magnetic moment that arises from the spin angular momentum of a spin-active nucleus. [1] If the element of interest has a nuclear spin that is not 0, [1] the nucleus may exist in different spin angular momentum states, where the energy of these states can be affected by an external magnetic field.
In NMR spectroscopy, the Solomon equations describe the dipolar relaxation process of a system consisting of two spins. [1] They take the form of the following differential equations : [ 2 ] d I 1 z d t = − R z 1 ( I 1 z − I 1 z 0 ) − σ 12 ( I 2 z − I 2 z 0 ) {\displaystyle {d{I_{1z}} \over dt}=-R_{z}^{1}(I_{1z}-I_{1z}^{0})-\sigma _{12 ...
Bruker 700 MHz nuclear magnetic resonance (NMR) spectrometer. Nuclear Magnetic Resonance (NMR) basic principles. Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are disturbed by a weak oscillating magnetic field (in the near field [1]) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic ...
