Cb. Roberts et al., SPECTRAL SHIFTS IN THE TRIPLET TRIPLET ABSORPTION-SPECTRUM OF ANTHRACENE IN SUPERCRITICAL FLUIDS, Journal of the Chemical Society, Chemical Communications, (10), 1993, pp. 868-869
Spectral shifts are observed in the triplet-triplet absorption bands o
f anthracene in supercritical fluids compared to those observed in nor
mal liquids and are attributed to London dispersion forces and local s
olvent density enhancements.
