Chlorophyll characterized by a porphyrin ring and a hydrophobic tail which anchors the molecule to the membrane. ! The porphyrin ring is host to the electronic states that participate in the interaction with light.! The spectrophotometer permits the measurement of absorption as a function of the incident wavelength. ! Note that chlorophyll appears green because it absorbs strongly in the blue and the red. ! We will be interested in examining the quantum mechanical underpinnings of absorption
