Capítulo 10
La Teoría de RPECV y las Estructuras Basicas
Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure, including approximate bond angles around…
La Toría RPECV y el Efecto de los Pares de Electrones Solitarios
It is important to note that electron-pair geometry around a central atom is not the same thing as its molecular structure. Molecular structure…
Prediciendo la Geometría Molecular
The following procedure uses VSEPR theory to determine the electron pair geometries and the molecular structures: Write the Lewis structure of…
Estructura Molecular y Polaridad
Polar covalent bonds connect two atoms with differing electronegativities, leaving one atom with a partial positive charge (δ+) and the other…
Teoría del Enlace de Valencia
Valence bond theory describes a covalent bond as the overlap of half-filled atomic orbitals (each containing a single electron) that yield a pair…
Hibridación de Orbitales Atómicos I
The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an…
Hibridación de Orbitales Atómicos 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,…
Teoría del Orbital Molecular I
Molecular orbital theory describes the distribution of electrons in molecules in the same way as the distribution of electrons in atoms is…
Teoría del Orbital Molecular 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 del impulsada por el láser ultrarrápido Molecular Rotación
We present a method for visualizing laser-induced, ultrafast molecular rotational wave packet dynamics. We have developed a new 2-dimensional Coulomb…
Hamiltonianos excitónicos para calcular espectros de absorción óptica y propiedades optoelectrónicas de agregados y sólidos moleculares
Rational design of disordered molecular aggregates and solids for optoelectronic applications relies on our ability to predict the properties of such…
Sondear la estructura y dinámica del agua superficial con túnel microscopía de barrido y espectroscopia
Water/solid interfaces are ubiquitous and play a key role in many environmental, biophysical, and technological processes. Resolving the internal…
