Question

In one form of this technique, distortionless enhancement by polarization transfer is an alternative to the APT. (10[1])The (10[1])Karplus equation relates (10[1])dihedral angles to the coupling constant (10[1])measured in this technique. (10[2])Most forms (10[1])of this technique use a Fourier (10[2])transform (-5[2])to analyze (-5[2])the free (10[1])induction decay (10[1])that occurs as a result (-5[1])of relaxation. TMS is used (10[1])as a standard (10[1])in several forms (10[1])of this technique, (10[1])which (-5[1])normalizes (10[1]-5[1])frequencies (-5[1])of peaks to chemical (-5[1])shift. (10[4]-5[2])This technique’s (10[1])most (-5[1])common forms (10[1])use hydrogen-1 (10[3])and (10[1])carbon-13 (10[3]-5[1])since they have a (10[1])non-zero (10[1]-5[1])spin. (-5[1])For 10 points, name this technique where chemical structures are determined by a strong (-5[1])magnetic (-5[2])field (10[2])applied (-5[1])to nuclei. (10[3])■END■ (10[6]0[11])
