Hello all,
Researchers in my department are interested in purchasing a system to
perform experiments that are, to me, a bit unusual. In the broad sense
they want to be able to detect correlations between two 'X' nuclei (in
liquids). A specific case is correlating 31P and 99Tc in
polyoxometalates. Other proposed experiments include correlating a
typical broadband nuclide with a low frequency one.
Does anyone out there have a probe that can perform such experiments? If
so, who made it? And, given the low sensitivity of many of these
nuclides, how much success have you had in detecting such correlations.
Varian and Bruker would like to sell us something. Yet, these probes are
clearly not routine. They are not exactly jumping up and down to give us
exactly what we'd like. Who made your probe? Does it have a narrow or
wide tuning range?
I've got a background in macromolecular, biochemical NMR. Therefore,
this area is a bit outside my expertise. Yet, the most generic, and
accessible example of these types of experiments would be 13C to
deuterium correlations (Please exclude this specific correlation from
any responses). So, this type of experiments/probes are feasible, no?
Why do Bruker and Varian keep wanting to sell us an inverse probe for
this application?
Lastly, is there any specific hardware that the console should have
outside of three (or four) channels, low frequency generator, etc.?
Thank you for your attention and any guidance that you can provide,
Matthew
