Thanks to those that responded to my inquiry about the chemical shift
temperature dependence of H2O. The answer of course depends on it's purity
and/or what it is mixed with. The only multiple reference I got was:
Hoffman, R. E. and Davies, D. B., Magnetic Resonance in Chemistry, Vol. 26,
523-525 (1988).
They reported values ranging from 0.0008 ppm per degree C to 0.016 ppm per
degree C. Other references that people submitted (which I have not read
for a variety of reasons like time, availability here on campus, etc.) are:
J. Phys. Chem 1995, 99, 6301
J.N.S Evans; Biomolcular NMR Spectroscopy; Oxford University Press; (1995).
J.L. Markley, B.D. Sykes et al; J. Biomol. NMR; 6; (1995); 135-140.
Lundberg P (1989) PhD thesis, U of Calgary, Canada.

Thanks again to all who replied!
