The electronic absorption spectrum UI (Cr(NH3)6]3+ (aq) is shown in Figure 11.5. One of the observed peaks is centered at about 303 nm. 1.a. What is the approximate value of the wavelength for the two other peaks? Which one of these three peaks falls in the visible region of the electromagnetic spectrum? The wavelength at this peak is (Amax), and this transition accounts for the color of the complex ion in solution. The energy of the transition occurring at...

If you were asked to design an experiment so that photosynthesis could be measured directly, what factors might you measure? 8. Compare your results for the absorption spectrum and the action spectrum. Explain any discrepancies between the wavelengths of light that are absorbed maximally and those wavelengths that cause the greatest photosynthetic activity.
