Hindered Rotation in Molecules with Relatively High Potential Barriers

摘要: The theory of hindered rotation has been applied to the type asymmetric molecule in which hindering barrier is high enough so that splittings energy levels are small compared with rotational energies but yet large be observable microwave spectrum. specific considered consists a rigid component may undergo about symmetry axis symmetric where addition assumed have threefold and at least plane containing component. An example might acetaldehyde molecule, CH3CHO.In principle, developed by Burkhard Dennison can used directly practice method difficult apply such since matrix elements Hamiltonian previously do not degenerate naturally or easily those for rotator i...
