To translate a given sw and o1p to spectral limits, use leftlimit = o1p + sw/2 rightlimit = o1p – sw/2 For example, o1p = 6ppm and sw = 20ppm translates into a window of -4ppm to 16ppm. Converting a… Read More
The procedure for running two dimensional spectra follows in general the procedure for one dimensional experiments with some modifications. Preparatory experiments It is recommended to always take a proton spectrum to verify sample purity, assess concentration and later use to… Read More
The NOE (Nuclear Overhauser Effect) experiment allows for the estimation of through space proton-proton distances. The two dimensional version will capture all possible pairs of protons, but can be lengthy and lack resolution. A one dimensional version of the experiment… Read More
Deuterated solvent.typically used in NMR play several roles: Reducing Solvent signal, that otherwise may overwhelm sample signals internal calibration of ppm axis using shift of solvent signal Long term stability of field using deuterium Lock The topshim automatic shimming uses… Read More
GENERAL In two dimensional experiments resolution in the indirect dimension is usually limited. The default spectral width settings for many experiments are therefore more restrictive and may not include chemical shift regions towards the edge of the range. For example… Read More
