Kapitel 10
VSEPR-Theorie und die Grundformen
Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure, including approximate bond angles around…
VSEPR-Theorie und die Wirkung von Einzelpaaren
It is important to note that electron-pair geometry around a central atom is not the same thing as its molecular structure. Molecular structure…
Vorhersage der molekularen Geometrie
The following procedure uses VSEPR theory to determine the electron pair geometries and the molecular structures: Write the Lewis structure of…
Molekülform und Polarität
Polar covalent bonds connect two atoms with differing electronegativities, leaving one atom with a partial positive charge (δ+) and the other…
Theorie der Valenzbindung
Valence bond theory describes a covalent bond as the overlap of half-filled atomic orbitals (each containing a single electron) that yield a pair…
Hybridisierung von Atomorbitalen I
The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an…
Hybridisierung von Atomorbitalen 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,…
Molekülorbitaltheorie I
Molecular orbital theory describes the distribution of electrons in molecules in the same way as the distribution of electrons in atoms is…
Molekülorbitaltheorie 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 von lasergetriebenen Ultrakurz Molecular Rotation
We present a method for visualizing laser-induced, ultrafast molecular rotational wave packet dynamics. We have developed a new 2-dimensional Coulomb…
Excitonic Hamiltonians for Calculating Optical Absorption Spectra and Optoelectronic Properties of Molecular Aggregates and Solids
Rational design of disordered molecular aggregates and solids for optoelectronic applications relies on our ability to predict the properties of such…
Erforschung der Struktur und Dynamik von Grenzflächen Wasser mit Scanning Tunneling-Mikroskopie und Spektroskopie
Water/solid interfaces are ubiquitous and play a key role in many environmental, biophysical, and technological processes. Resolving the internal…
