Display spin specific parameter values.
param: The parameter to display. Only one parameter may be selected.
scaling: The factor to scale parameters by.
The values corresponding to the given parameter will be displayed. The scaling argument can be used to scale the parameter values. This can be useful for example in the case of the model-free Rex parameter to obtain the spectrometer dependent value from the omega_ex field strength independent internal value. Or to scale correlation times from seconds down to nanosecond or picosecond timescales.
Please see Table 17.33 on page .
Please see Table 17.9 on page .
Please see Table 17.34 on page .
For model-free theory it is assumed that Rex values are scaled quadratically with field strength. The values will be very small as they will be written out as a field strength independent value. Hence use the following formula to convert the value to that expected for a given magnetic field strength:
Rex = value * (2.0 * pi * frequency) ** 2
The frequency is that of the proton in Hertz.
Please see Table 17.11 on page .
Please see Table 17.12 on page .
Please see Table 17.5 on page .
To show all CSA values, type:
[numbers=none] relax> value.display('csa')
To display the model-free Rex values scaled to 600 MHz, type one of:
[numbers=none] relax> value.display('rex', scaling=(2.0*pi*600e6)**2)
[numbers=none] relax> value.display(param='rex', scaling=(2.0*pi*600e6)**2)
