degenerate orbitals造句

• The superscript three ( read as Hund's rule which favors the single filling of degenerate orbitals.
• In particular they established how superexchange interactions, usually described by the Anderson-Kanamori-Goodenough rules, change in the presence of degenerate orbitals.
• All things ( values of the " n " and " m " l quantum numbers ) being equal, the order of stability of electrons in a system from least to greatest is unpaired with no other electrons in similar orbitals, unpaired with all degenerate orbitals half filled and the most stable is a filled set of orbitals.
• Two less stable, higher energy excited states are readily accessible from this ground state, again in accordance with Hund's first rule; the first moves one of the high energy unpaired ground state electrons from one degenerate orbital to the other, where it " flips " and pairs the other, and creates a new state, a singlet state referred to as the 1 ? g state ( a term symbol, where the preceding superscripted " 1 " indicates it as a singlet state ).
• Under most common laboratory conditions, the higher energy 1 ? singlet state rapidly converts to the more stable, lower energy 1 ? g singlet state; it is this, the more stable of the two excited states, the one with its electrons remaining in separate degenerate orbital but no longer with like spin, that is referred to by the title term, " singlet oxygen ", commonly abbreviated 1 O 2, to distinguish it from the triplet ground state molecule, 3 O 2.
