Prof. Geacintov is now
the Chairman of the Chemistry Department, and an outstanding researcher
in the chemistry and photophysics of DNA. In the early 1960’s, Prof.
Geacintov joined my research group at the RSSL as
a Research Scientist, and carried out the major experiments in that
period.He played a major
role in carrying out and interpreting the effect of a magnetic field on
the fission of tetracene singlets into geminate pairs of triplet
excitons.
