Abstract

 

The absorption and fluorescence spectra of 1-1` Binaphthalene (1-1` BN) molecule have been studied at different solution states in polar and non polar solvents at room temperature. It is noticed that the absorption spectrum of this molecule is similar to that of Naphthalene molecule at this temperature. The fluorescence spectrum of 1-1`BN molecule differs from that of the Naphthalene molecule. It is also found that a peak shifted towards shorter wavelength in the fluorescence spectrum when the solvent is changed. This is due to the polarity of the polar solvent.

 

Key words: Absorption spectra, fluorescence spectra, aromatic molecule, Solvent effect.
