The primary pathways of the photodecomposition of 9‐fluorenol (FOH) were studied in polar and nonpolar solvents by use of laser flash‐photolysis with a resolution time of 10 ps. In solvents of high polarity, that is, in 1,1,1,3,3,3‐hexafluoroisopropanol (HFIP), 2,2,2‐trifluoroethanol (TFE), formamid...
