Dear AMMRL members,
One of our faculty used to use a solution of at least two different organic
compounds whose 13C shifts could be used to measure the temperature of an
nmr probe to lower than -80C. He no longer has either the sample or the
literature reference and would appreciate hearing if any of you might be
able to recall seeing a reference to such a temperature standard.
Chuck
