The reason for the fact that the value λ max values and intensities of the UV absorption of styrene ( PhCH=CH 2 ) and phenylacetylene ( PhC ≡ CH ) are almost identical despite of the fact that phenylacetylene contains an additional π bond is to be stated. Concept introduction: Spectroscopy method is used to identify the structure of the molecule. It is based on the interactions between matter and electromagnetic radiations. Molecules have bonding or non-bonding electrons that can absorb light while promoting electrons from the ground state to an excited state. The light absorbed is usually in the UV or visible region. Conjugation in the molecule also affects the wavelength of light absorbed.
