NMR Chemical Shifts of Common Laboratory Solvents as Trace Impurities
Hugo E. Gottlieb, Vadim Kotlyar, and Abraham Nudelman
J. Org. Chem. 1997, 62, 7512-7515
% Temperature Dependence of HDO Chemical Shifts:
% δ = 5.060 - 0.0122T + (2.11 × 10-5 )T^2
% which reproduces the measured values to better than 1 ppb. For the 0 - 50o C range, the simpler
% δ = 5.051 - 0.0111T
% gives values correct to 10 ppb. For both equations, T is the temperature in °C.

Dear all,
I wonder if any of you have a chart of the chemical shifts of water at different temperatures. I remember seeing one, but am having a hard time finding it again. Thank you!
