## Abstract

Experimental investigations of magnetic field dependent kinetics of singlet fission (SF)processes in some organic semiconductors \[i.e. splitting of excited singlet (S\_1) state into a triplet exciton pair\] have revealed the important specific feature of obtained kinetic curves, associated with decaying intensities I(t) of fluorescence from S\_1-state. Kinetic curves, measured in different magnetic fields, are found to cross each other. We show that this kinetic curves crossing (KCC) effect is a general feature of geminate condensed phase reactions, resulting from simple characteristic properties of kinetic schemes of processes. Specific features of the KCC-effect are analyzed in detail with some models of SF-processes.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
