Question

Using the information provided below, derive an expression to show that the energy of electronic transition measured from UV-VIS spectroscopy is a function of the wavelength of the light absorbed using the equations below. Circle your final answer! ? lambda = c Delta E = h nu where E is the energy for the transition, v is the frequency of light, lambda is the wavelength, c and h are the speed of light and Plank's constant respectively (both constants) From the above derived equation, as the absorption maximum ( max) 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?

Explanation / Answer

as it is moving to longer wave length energy of radiation will decrease

so electronic transitions happens at lower energy levels compared to before case.
