Unformatted text preview: The porphyrin ring is host to the electronic states that participate in the interaction with light. Beer’s Law 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 spectra.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
