Dear Roger,
Water is (or at least was until IUPAC adopted a new system last year) the
standard for 17O chemical shifts. Therefore, I doubt if anyone has measured
its dependence on pH and temperature. You can see the signal in pure water
in a few scans at natural abundance, after all it is 55 molar.
Yours,
