title: Phase-independent ratio parameters for saturation transfer EPR.
abstract: Molecular dynamics have been studied by saturation transfer EPR. Rotational correlation times are obtained from the quadrature signal, as a ratio of spectral intensities at different field positions. It is possible to define ratio parameters that are independent of the phase of the modulation, but that can reduce to ratio parameters previously defined.
