uf.desc[-1].add_paragraph("For the proper measurement of relaxation data,
per-experiment temperature calibration is essential. This user function is
not for inputting standard MeOH/ethylene glycol/etc. calibration of a
spectrometer - this temperature setting is of no use when you are running
experiments which pump in large amounts of power into the probe head.")
-uf.desc[-1].add_paragraph("The R1 experiment should be about the same
temperature as a HSQC and hence be close to the standard MeOH/ethylene glycol
sepectrometer calibration. However the R2 CPMG or spin lock and, to a lesser
extent, the NOE pre-saturation pump a lot more power into the probe head.
The power differences can either cause the temperature in the sample to be
too high or too low. This is unpredictable as the thermometer used by the VT
unit is next to the coils in the probe head and not inside the NMR sample.
So the VT unit tries to control the temperature inside the probe head rather
than in the NMR sample. However between the thermometer and the sample is
the water of the sample, the glass of the NMR tube, the air gap where the VT
unit controls air flow and the outside components of the probe head
protecting the electronics. If the sample, the probe head or the VT unit is
changed, this will have a different affect on the per-experiment temperature.
The VT unit responds differently under different conditions and may
sometimes over or under compensate by a couple of degrees. Therefore each
relaxation data set from each spectrometer requires a per-experiment
calibration.")
