1. Complete the following table to estimate the wavelength of bromocresol green under the fol- lowing conditions. Recall that the color of a solution as perceived by your eyes is the complement of the color of light absorbed by the solution. This means that if an object looks deep blue, it absorbs yellow light preferentially. Wavelength Complement Color Color Observed Absorbed Base form (In¯) nm Equimolar acid and base nm Acid form (HIn) nm 630-720 nm 400-420 nm violet red deep orange blue light blue yellow yellow- green green 490-530 nm 530-545 nm 580-630 nm 420–450 nm 450-490 nm 545-580 nm

Part 1: Using the information provided below, derive an expression to show that the energy of an electronic transition measured from UV-VIS spectroscopy is a function of the wavelength of the light absorbed using the equations below. ν λ = cΔE = hν where E is the energy for the transition, ν is the frequency of light, λ is the wavelength, c and h are the speed of light and Plank's constant respectively (both constants). Part 2:From the derived equation, as the absorption maximum (λmax) for a molecule increases to a longer wavelength (for example from 300 to 700 nm), how does this affect the energy for the electronic transition?
