What do HOMO and LUMO correspond to?HOMO and LUMO:To put or excite an electron there are two highest energy molecular orbitals. The HOMO is the highest energy molecular orbital where an electron can exist. The LUMO is the next highest energy orbital which is empty. ...
What is the difference between LUMO and HOMO? Molecular Orbitals: Molecular orbitals are those which specify the location and wave-nature of an electron present in an atom. Also, they provide us the probability of discovering the electrons in a certain region of an atom. ...
A. 反应2NO®N2 +O2由于反应物的HOMO与LUMO对称性禁阻而不能发生 B. FMO理论适用于任何反应 C. FMO理论所指的对称性允许是指一分子的HOMO与另一分子的LUMO的位相一致 D. 用FMO理论判断一个反应能否发生时要满足对称性允许、能量相近、最大重叠原则 参考答案:C) 查看完整题目与答案 歌曲乐句与乐句之...
Conjugated organic molecules contain alternating double bonds between their carbon atoms, meaning their bonds are delocalized into shared electron clouds. The delocalisation of electrons results in a smaller HOMO-LUMO energy gap, meaning the promotion of an electron from the HOMO to the LUMO is ...
aThe charge-doping could introduce a polaron level between the HOMO and LUMO levels, which results in a narrow er frontier orbital energy gap, lower exitation energy, and smaller bond length alternation parameter comparing to the undoped system. 充电掺杂能介绍一个polaron水平在拉人之间和 LUMO水平,...

Examination of HOMO-LUMO energy levels show that aza-Diels-Alder reactions are HOMO (diene)-LUMO (dienophile) controlled and that the most electron deficient imines should be more reactive than simple alkyl or aryl imines and imines possessing less electron withdrawing groups. Evidence is also ...
