价层电子对互斥理论(VSEPR) 和基本形状
Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure, including approximate bond angles around…
价层电子对互斥理论(VSEPR) 和孤对的影响
It is important to note that electron-pair geometry around a central atom is not the same thing as its molecular structure. Molecular structure…
预测分子几何结构
The following procedure uses VSEPR theory to determine the electron pair geometries and the molecular structures: Write the Lewis structure of…
分子形状和极性
Polar covalent bonds connect two atoms with differing electronegativities, leaving one atom with a partial positive charge (δ+) and the other…
价键理论
Valence bond theory describes a covalent bond as the overlap of half-filled atomic orbitals (each containing a single electron) that yield a pair…
原子轨道的杂化方式 I
The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an…
原子轨道的杂化方式 II
To describe the five bonding orbitals in a trigonal bipyramidal arrangement, we must use five of the valence shell atomic orbitals (the s orbital,…
分子轨道理论 I
Molecular orbital theory describes the distribution of electrons in molecules in the same way as the distribution of electrons in atoms is…
分子轨道理论 II
The relative energy levels of atomic and molecular orbitals are typically shown in a molecular orbital diagram. For a diatomic molecule, the atomic…
激光驱动的超快分子旋转直接成像
We present a method for visualizing laser-induced, ultrafast molecular rotational wave packet dynamics. We have developed a new 2-dimensional Coulomb…
用于计算分子聚合和固体光学吸收光谱和光电特性的外化学汉密尔顿
Rational design of disordered molecular aggregates and solids for optoelectronic applications relies on our ability to predict the properties of such…
用扫描隧穿显微镜和光谱法探讨界面水的结构和动力学
Water/solid interfaces are ubiquitous and play a key role in many environmental, biophysical, and technological processes. Resolving the internal…
