According to free-electron molecular orbital theory, the electrons in molecular are regarded as independent particle that in a box with the length L. (a)Draw two molecular orbital shape occupied at butadiene predicted by this model and predict the minimum excitation energy of the molecular. Tetraene can be considered a box with the length 8R, R is 140pm. (b)Calculate the minimum excitement energy and draw
Electronic Transitions and Spectroscopy
The term “electronic” connotes electron, and the term “transition” implies transformation. In a molecule, the electrons move from a lower to a higher energy state due to excitation. The two energy states, the ground state and the excited state are the lowest and the highest energy states, respectively. An energy change is observed with this transition, which depicts the various data related to the molecule.
Photoelectron Spectroscopy
Photoelectron spectroscopy (PES) is a part of experimental chemistry. It is a technique used in laboratories that involves projecting intense beams of radiation on a sample element. In response, the element ejects electrons for which the relative energies are measured.
