The software includes PDF report generation, spectrum prediction (database-trained and/or algorithm based), structure drawing, structure search, spectrum search, text field search, and more. Access to the databases is available to subscribers either as NMR only or combined with mass spectrometry and FT-IR data.
Modeller, often stylized as MODELLER, is a computer program used for homology modeling to produce models of protein tertiary structures and quaternary structures (rarer). [2] [3] It implements a method inspired by nuclear magnetic resonance spectroscopy of proteins (protein NMR), termed satisfaction of spatial restraints, by which a set of geometrical criteria are used to create a probability ...
Because of the magnitude and severity of the problems with chemical shift referencing in biomolecular NMR, a number of computer programs have been developed to help mitigate the problem (see Table 1 for a summary). The first program to comprehensively tackle chemical shift mis-referencing in biomolecular NMR was SHIFTCOR. [2] Table 1.
Advanced Chemistry Development, Inc., (ACD/Labs) specializes in the design of software, with a focus on the R&D and chemistry of molecules ('small molecules').They offer software for tasks including analytical data handling and knowledge management; in addition, molecular property modelling and property-based design are relevant areas of expertise in ACD Labs.
While at ACD/Labs Williams was involved in a number of industry firsts [citation needed] including producing a chemical dictionary on a Palm Computer and Pocket PC, [31] working with Gary E. Martin and other colleagues to develop new NMR processing techniques using covariance-based approaches, [32] [33] [34] [35]
Free induction decay (FID) nuclear magnetic resonance signal seen from a well shimmed sample. In Fourier transform nuclear magnetic resonance spectroscopy, free induction decay (FID) is the observable nuclear magnetic resonance (NMR) signal generated by non-equilibrium nuclear spin magnetization precessing about the magnetic field (conventionally along z).
A phenomenological definition of the NOE in nuclear magnetic resonance spectroscopy (NMR) is the change in the integrated intensity (positive or negative) of one NMR resonance that occurs when another is saturated by irradiation with an RF field. The change in resonance intensity of a nucleus is a consequence of the nucleus being close in space ...
Proton nuclear magnetic resonance (proton NMR, hydrogen-1 NMR, or 1 H NMR) is the application of nuclear magnetic resonance in NMR spectroscopy with respect to hydrogen-1 nuclei within the molecules of a substance, in order to determine the structure of its molecules. [1]
