Molecular Orbitals and Vibrational Energy Levels When atoms are bonded together, new kinds of energy levels are created. A single atom has only electron energy levels; a molecule has special molecular electron energy levels, as well as vibrational and rotational energy levels. As atoms covalently bo...
The nodal structure of the electronic orbitals is stressed as the common underlying theme in such effects as: the Peierls distortions of metallic systems; the changing electron counts (due to charge transfer or different d-electron counts); the high-pressure transformations of solids. The range of...
Energy levels and orbitals help describe the electronic structure of an atom. They designate how electrons are arranged within atoms, and the description of such energies is derived from quantum theory. Quantum Theory Quantum theory postulates that atoms can only exist in certain energy states. If ...
It can be seen in the above diagram, orbitals 2s and 2p are not placed at the same levels i.e. they do not possess the same energy as each other. The orbitals having lower energy are placed nearer to the nucleus. i.e the order s, p, and so on shows that orbitals have lower ene...
The sets of orbitals with the same n value are often referred to as electron shells or energy levels. 相同n值所对应的轨道经常被称作原子壳层,对应能量值称为能级。 LASER-wikipedia2 Due to spin-orbit coupling between the d electrons, this state is split into a pair of energy levels. 由...

In the terminology of simple molecular orbital theory, for example, excitation of electrons into nonbonding or antibonding orbitals leads to an electronic state that is less tightly bound, and therefore the force constant is reduced from that observed in the ground state. The spacing between ...
A large number of the observed energy levels have been assigned to specific Nilsson orbitals and their superimposed rotational bands. Generally, the energy systematics of the Nilsson bands qualitatively follow expectations of the Nilsson model. The energy systematics, decoupling parameters, and cross ...
