Ethene: Franck-Condon Active
       
 

Using symmetry to determine absorption mechanism

Ethene is a test case to study the complete treatment of molecular symmetry using LCAO-MO theory. Computational appraoches can generate the energies of the states and group theory can be used to deermine, which transitions are allowed.
