— Fluorescence behaviour of chlorophyll‐ a in a liquid crystalline medium, dodecyl cyanobiphenyl, has been investigated as a function of temperature and concentration. At concentrations of 6 times 10 ‐4 M , emission in the Q‐band region exhibited peaks in the crystal at 650,695 and 735 nm as well as the monomer band at 675 nm. Dilution studies indicate that these additional bands probably arise from aggregation of the chlorophyll.
