Polycyclic Aromatic Hydrocarbon Compound

Polycyclic aromatic hydrocarbon compound, 1,2 : 3,4-dibenzanthracene, is spectroscopically analyzed in ethanol. Ultraviolet absorption spectra were taken and fluorescence measurements were performed. From absorption and emission spectra, Stokes' lines were clearly discernible and these shifts were recorded. Being a carcinogenic compound, the detection of 1,2 : 3,4-dibenzanthracene presence in the environment as a pollutant with adverse genotoxic effects is vital.

Fluorescence properties of benzo[ghi]perylene (BPe) and ovalene (Ov) dissolved in 25 solvents of varying polarity are reported. Measurements indicate that emission intensities depend on solvent polarity. The BPe and Ov solvent polarity scales are defined as the ratio of the fluorescence emission intensities of bands I and III of the vibronic spectra. Benzo[ghi]perylene and ovalene solute probes enable fluorescence measurements to be made in spectral regions less prone to solvent inner filtering and other artifacts which have hampered the use of pyrene (Py) as a polarity probe molecule.
