Optical nuclear polarization via hyperfine relaxation. Polarization mechanism in anthracene/tetracyanobenzene charge-transfer crystals

The large optical nuclear polarization (ONP) found in A/TCNB crystals is due to relaxation caused by the mobility of triplet excitons. The ONP field dependence gives an excitonic hopping rate of 3 × 10 9 s −1 (at 300 K). Exclusion of ONP by static hyperfine interaction (LAC ONP) is based on results...

Description
Summary:The large optical nuclear polarization (ONP) found in A/TCNB crystals is due to relaxation caused by the mobility of triplet excitons. The ONP field dependence gives an excitonic hopping rate of 3 × 10 9 s −1 (at 300 K). Exclusion of ONP by static hyperfine interaction (LAC ONP) is based on results of rf ONP experiments which allow an unambiguous distinction between the two processes.
