-
Copy an existing 1D zgesgp experiment (pulse program: zgesgp). Or in an new experiment "rpar P3919GP all" and change the pulse program to zgesgp.
-
Type eda, in the acquisition parameter window check and adjust td, ns, ds, sw.
-
Type ased, in the pulse program parameter window, enter calibrated p1, pL1 values, and O1 determined from 1D zgpr experiment. Or type "getprosol 1H A B" to set power related parameters. A is the pulse length in µs, and B is the power leverl in dB.
-
In gs mode adjust p12 to achieve minimum FID area integral.
-
Start the experiment by rga and zg;
-
Process the FID by typing “dfp”, and phase the spectrum when necessary.
