Calculate the energy in Ws dissipated in the probe head coil for a spin lock lasting 300 ms and an individual 90° pulse of 40 Ps at 12 dB using a 100 Watt 1H ampli¿er. Compare this energy with a 10 Ps hard pulse at – 6 dB which corresponds to maximal power.

Phase correction is not necessary, since the data are processed in magnitude mode. After the Fourier transformation the 2D spectrum is tilted, since the signals are also modulated by J in F2. This tilt can be eliminated by a software command. Finally the data may be symmetrized with respect to the horizontal through the center of F1. 3 5 6 CDCl3 GH / ppm Fig. 1-1 2D J-resolved 1H NMR spectrum of 1-Àuor-2,4-dinitrobenzene above: 2D projection in F2; below: 1D spectrum for comparison 38 J-Resolved 1H NMR 6.
