I'm trying to get the SELINCOR experiment working and have to
calibrate the shaped pulse on the decoupler channel first. I'm using
experiment 7.3 from Braun/Kalinowsk/Berger's 150 and More Basic NMR
Experiments for the calibration. It works to the extent that I can get the
antiphase doublets but changing power levels for the shaped pulse doesn't
seem to affect things at all.
I'm wondering if I might be using an incorrectly written the pulse
program and if anyone has a version for the AMX spectrometer that works.
Here is what I have been using:
1 ze
2 d1 s1 ;switch to high power
p1 ph1
d2 s2 ;low power for spin lock
(p2 ph1) (p4 ph1):dp1
go=2 ph31
wr #0
exit
ph1= 0
