Va. Bagryansky et al., QUANTUM BEATS IN THE RECOMBINATION OF RADICAL-ION PAIRS CAUSED BY HYPERFINE INTERACTION IN RADICAL-ANIONS, Mendeleev communications, (4), 1997, pp. 132-133
Quantum beats in the recombination fluorescence of 1,2,3,3-tetraphenyl
cyclopenta-1,3-diene and 2,3,4,5-tetraphenyl-1-germacyclopenta-2,4-die
ne radical anions have been detected and the hfc constants in these sp
ecies determined.
