The sensitivity of this technique is improved by employing CryoProbes with continuous liquid helium streams. (10[1])The DISPEL method is applied during this technique to remove “satellites” shouldering primary signals. Chromium(III) acac (“ay-cack”) is used in this technique as a relaxation agent for (10[1])more (10[1])rapid scans. (10[2])One type of this technique (-5[1])applies 45-, 90-, and 135-degree (10[3])pulses (10[3])on the sample (10[6]-5[1])to induce (10[2])polarization (10[2]-5[1])transfer. (10[2]-5[1])Through-space (10[1])interactions are probed (10[1])by measuring the Overhauser (10[1])effect (10[1])in this technique, (10[4])one form of (10[1])which (10[1])requires concentrated samples due to the (-5[1])low one percent abundance of a natural isotope. (10[2]-5[1])Proton decoupling (10[2]-5[1])generates (10[2])singlet (10[2])peaks (10[2])with no (10[2])splitting (10[5])in this technique’s (10[4])13C (-5[1])variant. (10[6]-5[4])For (0[1])10 (10[1]-5[1])points, (10[2])name this (-5[1])analytical technique that applies a magnetic (10[1]-5[1])field on a sample. (10[1])■END■ (10[11]0[7])
