Bibliographies on radiation chemistry

The clarification of the nature of the 'phosphorescent state' of photoexcited organic molecules as the triplet state and its detection in absorption has led to the development of triplet-triplet absorption spectroscopy as an important tool in quantitative photochemistry. We have compiled a bibliography of papers dealing with triplet-triplet absorption spectroscopy which we hope is reasonably complete through February 1982. The number of references (about 800) has mandated the separation of this list into two parts. Part A includes work published before 1976; Part B from then until the above cutoff date. The initial set of references was obtained as a subset of a profile on transient spectra and by a retrospective literature search. This was augmented by various keyword searches of the RCDC bibliographic data base. The keywords (and logic) chosen were (triplet state and absorption spectra) or triplet-triplet absorption or triplet-triplet transition. Additional sources are also acknowledged. We have included only those papers providing quantitative spectral information such as peak locations and extinction coefficients. Studies in which the observation of a known triplet-triplet absorption is used simply as a kinetic tool have generally been omitted. Work in the gas phase has been excluded and we have not covered the theoretical aspects of the phenomenon. (author)
