| Abstract: | The interaction between 9-fluorenone, various indoles and solvents has been studied using steady-state fluorescence spectroscopy and quantum chemical calculations. It was determined that polar protic solvents such as methanol and ethanol significantly quenched the fluorescence of 9-fluorenone but various indoles reversed the solvent quenching. The effect of various solvents on the 9-fluorenone carbonyl vibration was investigated using infrared spectroscopy. Ab initio calculations using Gaussian03 were also carried out in order to determine the minimum energy conformations of these systems along with binding energies. |
