Many versions of this technique use polarization transfer to enhance signals.
Many versions of this technique use polarization transfer to enhance signals. Sequential walking isused to correlate cross-peaks in two-dimensional forms of it. This technique can be used instead ofX-ray diffraction on small proteins in solution. TMS is used as a standard in this technique, in whichJ-couplings split signals and the integration gives the number of equivalent atoms. This techniquerelies on the fact that atoms in different chemical environments (*) oscillate at different frequencies. Itoperates by subjecting a solution of a molecule to a series of radio frequency pulses, and a variation of itused in medicine is the MRI. For 10 points, name this type of spectroscopy that uses very high poweredmagnets to determine chemical structures.
