C.J.Jameson, A.K.Jameson, & S.M.Cohen, J.Chem.Phys 62,4224-4226 (1975) --
"Temperature and density dependence of 129Xe chemical shift in rare gas
mixtures".

This is not _exactly_ the reference you want, but one in M.Magn.Resonance by
the same authors at about the same time. Since they locked to TMS, they had
to do a temp. calib. for the TMS absolute chem. shift, using as a reference
the 129Xe frequency extrapolated to zero pressure (and therefore independent
of temperature).

Hope this helps. I don't recall the exact reference. Some student borrowed
my copy of the paper, and........... :-(
