I received a number of requests to forward any responses to my Z-filtered
TOCSY query to the group so here they be! I received two responses. The
first, invigsmltp, is in the Bruker PP library and is for "2D H-1/X
correlation via double inept transfer using MLEV17 for homonuclear
Hartman-Hahn mixing." I should have specified in my post that I was
actually looking for homonuclear 1H-1H experiments but this experiment looks
like it will be useful for solving some other structural problems once we
get our new gradient system (hopefully next month!!!). Does anyone have the
literature reference describing this experiment?
The dipsi2st and dipsi2tp pulse programs with variable delay look like
they will accomplish exactly what I want to do, with one caveat, they are
written for DMX and are not in the AMX pulse program library. Rainer kindly
emailed them to me however and I can pass them on to anyone else who wants
them. They will need to be modified to AMX jargon rather than DMX but I
believe this should be a minor task.
Many thanks to Tony and Rainer for their assistance. If anyone would like
the above mentioned pulse programs, email me and I will send them to you.

Brian,
Do you have the pulse program
invigsmltp
on your system? I think this may be what you are after,
Regards,
Tony Pemberton

I found
dipsi2tp
within my pp library. To get even better phase quality you can
replace the both delays between the 90 degree pulses and the DIPSI
mixing sequence by a variable delay. Take about 7 different delays
with random values somewhat between 200 mikroseconds and
10 milliseconds.
Best regards
