Hi kmd,

You'll need to set frequency offset before the "t1" excitation pulse to whatever corresponds to 7 ppm - that will cause "t1" evolution to be encoded relative to the frequency of that pulse.

Similarly - to read relative to water resonance - set transmitter offset to the water offset value just before the readout pulse.

If you have a Varian system you would do something like:

pulsesequence(){
    double myoffset;
    ...
    myoffset = getval("myoffset");
    ...
    obsoffset(somevar);
    rgpulse(...);/* or simpulse, sim2pulse or sim3pulse */
    ...
}

}

Hope that someone will explain how to do this for a Bruker system.system or any other details.
