Capítulo 10
Teoria da VSEPR e as Formas Básicas
Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure, including approximate bond angles around…
Teoria da VSEPR e o Efeito de Pares Solitários
It is important to note that electron-pair geometry around a central atom is not the same thing as its molecular structure. Molecular structure…
Previsão da Geometria Molecular
The following procedure uses VSEPR theory to determine the electron pair geometries and the molecular structures: Write the Lewis structure of…
Forma e Polaridade Moleculares
Polar covalent bonds connect two atoms with differing electronegativities, leaving one atom with a partial positive charge (δ+) and the other…
Teoria da Ligação de Valência
Valence bond theory describes a covalent bond as the overlap of half-filled atomic orbitals (each containing a single electron) that yield a pair…
Hibridização de Orbitais Atómicas I
The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an…
Hibridização de Orbitais Atómicas 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,…
Teoria das Orbitais Moleculares I
Molecular orbital theory describes the distribution of electrons in molecules in the same way as the distribution of electrons in atoms is…
Teoria das Orbitais Moleculares II
The relative energy levels of atomic and molecular orbitals are typically shown in a molecular orbital diagram. For a diatomic molecule, the atomic…
Direct Imaging da Laser-driven Ultrafast rotação Molecular
We present a method for visualizing laser-induced, ultrafast molecular rotational wave packet dynamics. We have developed a new 2-dimensional Coulomb…
Hamiltonianos excitônicos para o cálculo de espectros de absorção óptica e propriedades optoeletrônicas de agregados moleculares e sólidos
Rational design of disordered molecular aggregates and solids for optoelectronic applications relies on our ability to predict the properties of such…
A estrutura e a dinâmica da água Interfacial com encapsulamento microscopia de varredura e espectroscopia de sondagem
Water/solid interfaces are ubiquitous and play a key role in many environmental, biophysical, and technological processes. Resolving the internal…
