Regulation Mode
The following steps need to be performed:
• Insert sample.
• Tune and match – atma.
• Lock-in – temperature value appears.
• Topshim.
• Selftune (maybe already done in example 1).
• Edte – enable NMR Thermometer.
• Perform an experiment with internal RF heating (e.g. TOCSY).
After setting up the system (lock, shim) and enabling the NMR Thermometer (edte) the
sample temperature is used for temperature regulation, which is visible on the status bar:
Figure 4.11: TopSpin status bar with NMR Thermometer enabled.
To test the performance of the NMR Thermometer start a TOCSY experiment and follow the
temperature values (sensor, NMR Thermometer) in the monitoring window of the VTU display
(edte). One can nicely see that the temperature inside the sample increases over a certain
