In the top frame of the Instruments tab of CcpNmr ECI, it is possible to specify the
NMR spectrometers that were used to run your NMR experiments. Here you can specify the
proton frequency (which will automatically update the nominal frequency field). There
is also a dropdown menu of common spectrometer manufacturers and, based on your choice
of manufacturer, a pulldown menu of spectrometer models. You can also indicate the
serial number and additional details about the spectrometer.
In the bottom frame, you can edit NMR probe information including probe type, manufacturer,
model, serial number and details.
