| Abstract | ||
| The mid Infrared, Near infrared, visible, and Ultra-violet spectra of Benzene molecule have been studied. Since Benzene molecule belongs to D6h point group, with very high symmetry elements, therefore it may be expected for its external vibrations to be either infrared or Raman active only. The mid infrared spectrum of the molecule shows only the active infrared fundamental and combination bands. However no overtone bands have been detected within this region because of its symmetry. The ultra -violet region shows cut off starting at (350 nm) due to d d* and π π* electronic transitions. However no absorption has been observed within visible region (400-800)nm, which is confirmed since pure benzene liquid has no color. | ||
