Dear Friends:
Thanks to a lot of people responding to my query "Invert two peaks in
T1 experiment". Several people want me to post summary of responses, it
sounds that this is an interesting subject. Here the summary is:

1. The simplest way is to use DANTE train of pulses. The length of
delay should be decided by the separation of the two peaks. The sum of all
pulses should equal a 180 degree pulse and the total length of the sequence
will determine the selectivity. It does not need waveform or pulse shaping
capacity on the spectrometer.
2. Use waveform generator to make shaped pulses and invert the two
peaks.
3. If the spectrometer can do dual decoupling, then the two peaks can
be inverted by adjusting the dual decoupling pulses.

Again, thanks to all responses.
