Hello NMR folks tuned in to BUM
My name is Lawrence Byrnes. The company that I work for is an independent
and totally self-supporting analytical NMR service organization. I will,
therefore, be careful that the material that I post will be non-commercial in
nature. My main interest in joining the group is to learn how make the most
of my 1983 vintage hardware and to keep same in good working order.
Numare is a one-person, one-instrument laboratory with a reconditioned
Bruker ACF-200 NMR system located in northern New Jersey. The magnet has a
5mm liquid state VSP-200 probe that is capable of observing 109Ag through
31P, 19F, and 1H. The computer is an Aspect 3000 with process controller,
array processor, 512K RAM, and 160 Meg hard drive. The system has a 35W
proton decoupler and a VT unit. 1D data processing is done on a PC with
WinNMR, via data transfer by NMRlink.
Several days ago, I read the subject lines of the archives from 1993 to
present in search of correspondence wrt multiple pulse line narrowing
techniques. I found only one querry some time in 1993 with no corresponding
response. Therfore, I will put the question out one more time:
Does anyone in BUMland have any firsthand experience in writing AU
programs, for the hardware listed above, that implement WAHUHA, WAHUHA-4,
MREV-8, HW-8, BR-24, BR-52, BLEW-12, or BLEW-48 pulse sequences?

The above provide good fundamental background but no practical
implementation.
