The particle in a box (PiB) model can be applied to electrons which move freely in a molecule such as π electrons. 1,3-butadiene CH2=CH-CH=CH2 has an absorption peak in the UV-Vis spectrum at 290 nm. This peaks is assigned to the π → π* transition of the lowest energy. This transition is also called the HOMO → LUMO transition. As a simple approximation, let’s consider molecule of butadiene as being potential 1D box of length 3 * 1.4 Å = 4.2 Å, when counting three carbon-carbon bonds each 1.4 Å long. Also let’s consider the four π electrons occupy molecular orbitals MOs and energy of MOs is calculated according to the PiB model. a) Sketch the scheme of MOs of butadiene molecule and populate them with electrons. b) Calculate the wavelength of light λcalc which corresponds to absorption of light and excitation of π electron from the HOMO to the LUMO in the molecule of butadiene. c) Compare this calculated λcalc with experimental value of λexp = 290 nm provided above, and explain the…

If the spacings between adjacent vibrational features in a photoelectron spectroscopy experiment decrease, changing by a factor of 1/2, when you deuterate the molecule being ionized, is it more likely that the orbital from which you are ejecting an electron is from a nonbonding orbital, a p orbital localized on a C-C or C-O bond, or a s orbital localized on a C-H bond? Explain.
The lowest absorption energy of simple organic molecules can often be predicted by approximating the molecule as a 1D particle in a box. Consider the molecule 1,3-butadiene, which consist of four Carbon atoms in a conjugated chain. Butadiene absorbs light at a wavelength of 310 nm. Assume we can model this molecule by only considering its T electrons occupying the energy levels of a 1D particle in a box. Approximating the absorption energy as a highest occupied to lowest unoccupied (HOMO to LUMO) orbital transition, find the size of the "box" that would correspond to an excitation wavelength of 310 nm (you have just found an estimate for the length of the 1,3 butadiene molecule!). Give your final answer in units of angstrom. In your work, also comment on whether you would expect the molecule octatetraene, which contains 8 C atoms in a conjugated chain, to absorb light at a higher or lower wavelength.
