jw_mapping.set_frq

Synopsis

Select which relaxation data to use in the J(ω) mapping by NMR spectrometer frequency.

Defaults

jw_mapping.set_frq(frq=None)

Keyword arguments

frq: The spectrometer frequency in Hz. This must match the currently loaded data to the last decimal point. See the `sfrq' parameter in the Varian procpar file or the `SFO1' parameter in the Bruker acqus file.

Description

This will select the relaxation data to use in the reduced spectral density mapping corresponding to the given frequency. The data is selected by the spectrometer frequency in Hertz, which should be set to the exact value (see the `sfrq' parameter in the Varian procpar file or the `SFO1' parameter in the Bruker acqus file). Note thought that the R₁, R₂ and NOE are all expected to have the exact same frequency in the J(ω) mapping analysis (to the last decimal point).
