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. |
