DANTE Pulses - A Different Way for Selective Excitation

In Check it 5.33.1 first the original DANTE sequence and the corresponding x-, y-and z-excitation profiles are simulated to show how the improved DANTE-Z sequence [5.120] was developed. 

The improved DANTE-Z sequence only differs from the original sequence by an additional pulse whose phase is cycled by a tt phase shift and a final 90° pulse to transfer the z-magnetization to detectable transverse magnetization. In Check it 5.3.3.2 the modification to the phase cycling in the original DANTE sequence is examined and the results of selective excitation using the DANTEl-1 and DANTE363 sequence compared. 

Load the file ch5332a.cfg. Calculate two FIDs for the danteprf.ham spin system file using the dantezl.seq and dantez2.seq pulse sequence. Process the FIDs (zero filling Sl(r+i) 64k, wdw EM, LB 1.0 [Hz]) and obtain the difference spectrum using the 

Simulate the 1D selective COSY spectrum of glucose using the configuration file ch5333.cfg. The experiment uses a DANTE-Z element for the selective excitation of the proton at 3.9 ppm. Note depending upon the computer speed this simulation may take several minutes.
