Look at this figure from Blankenship's book, Molecular Mechanisms of Photosynthesis. You can see the structure for bacteriochlorophyll a, along with its absorption spectrum. a. What is the molecular shape around the labeled carbon atom? b. What is the hybridization around that same carbon? c. Based on this structure, would you expect this molecule to absorb light in the visible spectrum? Why or why not? Absorbance Fluorescence (Arbitrary units)
