The energy levels for the particle-in-a-box model can be used to predict the energy required to excite an electron that is part of a conjugated systems. The electron is essentially a particle that is trapped In the conjugated system. Butadiene has 4 electrons that are part of the conjugated system, which, in the lowest energy conformation, can be considered to be in two energy levels (1 and 2). H 3 H H - 133.8 pm H 133.8 pm H -H 1 H H Calculate the wavelength of light (nm) needed to promote an electron from n=2 to n=3.
