Abstract

Absorption spectra of 9-fluorenone had been studied in polar and non-polar solvents. Maximum of four bands were observed; the shift in these band as the solvents were changed from polar to non-polar were noted. The quantitative treatments of the shifts allowed the transition to be assigned as n®p*or p®p*.

 

Key words: Fluorenone, electronic absorption, transition, excited state polar and non polar solvent.
