Question

In one form of this technique, distortionless enhancement by polarization transfer is an alternative to the APT. The Karplus equation relates dihedral angles to the coupling constant measured in this technique. Most forms of this technique use a Fourier transform to analyze the free induction decay that occurs as a result of relaxation. TMS is used as a standard in several forms of this technique, which normalizes frequencies of peaks to chemical shift. This technique’s most common forms use hydrogen-1 and carbon-13 (-5[1])since they have a non-zero spin. For 10 points, name this technique where chemical structures are determined by a strong magnetic field applied to nuclei. ■END■
