Question

Calculate the wavelength of radiation that would absorb from a molecule of porphyrin at the highest and lowest occupied energy levels. Poryphyrin has 22 pi electrons that can be idealized as particles on a ring with a radius of 0.50nm

g) Assume that the 22 r electrons in free base porphyrin (shown below) may be idealized as particles on a ring of radius 0.50 nm. What wavelength of radiation would it absorb for the excitation from the highest occupied energy level also called the molecular orbital (HOMO) to the lowest unoccupied energy level also called molecular orbital (LUMO)?
