Dear BUMmers,
Thanks to all who responded to my question regarding 1H observe, 19F
irradiated Difference NOE pulse program for a DPX system with a QNP probe.
The comments from Xiaohong Liu and efforts of Peter Ziegler were especially
helpful in coming up with a solution.
I have included the modified version of the zgf2pr pulse program, renaming
it hfnoeqn. The noediff au program also needs to be modified and renamed.
In the section which defines the spectrometer type (Avance), the line
STOREPAR('PULPROG","zgf2pr");
needs to be changed to:
STOREPAR('PULPROG","hfnoeqn");
;hfnoeqn
;avance-version
;1D sequence with f2 presaturation
;1H observe 19F irradiated difference NOE
;to be used in conjunction with the au program HFnoediff

;pl1 : f1 channel - power level for pulse (default)
;pl14: f2 channel - power level for cw decoupling
;p1 : f1 channel - 90 degree high power pulse
;d1 : relaxation delay; 1-5 * T1
;d11: delay for disk I/O [30 msec]
;d13: short delay [3 usec]
;d12: short delay [20 usec]
;NOTE in order for this to work, the rod from the QNP probe to the
;pneumatic switch drive must be disconnected at the switch drive
;and the rod pulled down to the appropriate 19F QNP setting (usually 3)
Thanks again,
Bill
