In a molecule, bonding or nonbonding electrons can be excited to higher antibonding molecular orbitals through absorbing photons, and this transition from ground states to excited states corresponds to the absorption of photons in absorption spectroscopy. The reverse transition from excited states to ...
Chemists explaining a molecule’s stability and reactivity often refer to the concepts of delocalization, resonance, and aromaticity. Resonance is commonly discussed within valence bond theory as the stabilizing effect of mixing different Lewis structures. Yet, most computational chemists work with delocal...

还原剂当然是失去电子,本身被氧化.放出能量,叫loses energy.gains energy是指储存起来. 分析总结。 正确答案是b老师和周围的老外都说是b我怎么都想不通结果一 题目 一道生物关于还原剂的题The molecule that functions as the reducing agent (electron donor) in an oxidation-reduction reactionA) gains electrons...
STM would be able to detect the vibrational signatures of the species in the junction making it possible to develop a chemical sensitivity absent in the usual STM operational modes; on the other hand-side, the extreme local sensitivity of the STM would permit to have a single-molecule spectrosc...
Part 1 || Fibronectin Molecule Visualized in Electron Microscopy: A Long, Thin, Flexible Strand We have determined the structure of plasma fibronectin by electron microscopy of shadowed specimens. the 440,000 molecular weight, dimeric molecule appears to be a long, thin, highly flexible strand. ...
Electron transport through a conjugated molecule with carbon nanotube leads 电子通过带碳纳米管导联的共轭分子的传递A model carbon nanotube (CNT)-(CH)n-CNT structure is studied to understand electron transport through an interface between two conjugated systems.我们研究了一个模型碳纳米管(CNT)-(CH)n-...
