In the case of nonvanishing exchange interaction, the singlet-triplet mixing will pass through a maximum at a field matching this interaction.

Femtosecond pump-probe measurements were performed with a Ti-sapphire laser system. The set-up and relevant pulse energies and durations are described in (10). Here, we restrict ourselves to the changes made to perform the field-dependent experiments. Pump and probe beams were crossed under a small angle in the center of a superconducting magnet. The propagation vectors of pump and probe beams were nearly perpendicular to the magnetic field; their polarizations were adjusted parallel with respect to each other and to the magnetic field in the measurements presented here. However, no influence of the relative polarization of pump and probe beam or pump and probe beam with respect to the field could be detected. For the recording of one time trace a certain field was set and kept constant during the measurements. By repeating the zero field time trace after a series of field measurements, we ensured the stability of the set-up and the sample.

For g tensor values of ethylferricenium, the corresponding values of ferricenium were used because no experimental values are available for the former. However, monoalkyl substitution has little influence on the g tensor, as demonstrated by the values of methylferrocenium [R. Prins and A. R. Korswagen, J. Organometal. Chem. 25, C74 (1970)].

Data analysis required deconvolution of experimental data of the experimental response function. The experimental response function was determined by two-photon absorption and modeled by a Gaussian function with a full width at half maximum (FWHM) of 180 fs. The experimental data were then fitted to a multiexponential function and an offset, both convoluted with the Gaussian function. The exponential terms were then taken as the deconvoluted experimental values that were fitted by the time-dependent solution of the stochastic Liouville equation by using the Levenberg-Marquardt method. The simulation curves on which the difference curves in Fig. 4 are based were obtained by numerically convoluting the theoretical curves for delta function - type RP population process with the 180-fs FWHM Gaussian.
