NMR spectra
« on: January 02, 2005, 07:45:20 AM »
I have the 129Xe NMR spectrum of XeF6 in solution. I would expect the monomeric structure to produce a spectrum with 7 peaks however the spectrum has 11 peaks. I am therefore guessing it is a polymer but I can't imagine what the structure would be like. Any ideas?

Those 4 extra peak could be rotation sidepeaks, but iI'd need to see the spectra to be sure.
Chemists do it periodically on table.

No he can't as that site doen't include 129Xe NMR.

READ the question before posting generic answers you half wit.

Abstract

In the study of the 129Xe-NMR spectra of simple Xe compds., the spectra of
Xe, XeF2, XeF4, XeOF4, and XeO3 were found to agree with the known
structures whereas XeF6 was found as Xe4F24 in inert soln. at low temps.
The coupling consts. vary between 330 Hz for Xe2F24 and 5550 Hz for XeF2.
