Capitolo 10
Teoria VSEPR e forme di base
Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure, including approximate bond angles around…
Teoria VSEPR ed effetto delle coppie solitarie
It is important to note that electron-pair geometry around a central atom is not the same thing as its molecular structure. Molecular structure…
Previsione della geometria molecolare
The following procedure uses VSEPR theory to determine the electron pair geometries and the molecular structures: Write the Lewis structure of…
Forma e polarità molecolare
Polar covalent bonds connect two atoms with differing electronegativities, leaving one atom with a partial positive charge (δ+) and the other…
Teoria del legame di Valence
Valence bond theory describes a covalent bond as the overlap of half-filled atomic orbitals (each containing a single electron) that yield a pair…
Ibridazione degli orbitali atomici I
The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an…
Ibridazione degli orbitali atomici 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 dell'orbitale molecolare I
Molecular orbital theory describes the distribution of electrons in molecules in the same way as the distribution of electrons in atoms is…
Teoria dell'orbitale molecolare 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 di laser-driven ultraveloce rotazione molecolare
We present a method for visualizing laser-induced, ultrafast molecular rotational wave packet dynamics. We have developed a new 2-dimensional Coulomb…
Hamiltoniani eccitonici per il calcolo degli spettri di assorbimento ottico e delle proprietà optoelettroniche di aggregati e solidi molecolari
Rational design of disordered molecular aggregates and solids for optoelectronic applications relies on our ability to predict the properties of such…
La struttura e la dinamica di acqua interfaccia con Tunneling di microscopia e spettroscopia di sondaggio
Water/solid interfaces are ubiquitous and play a key role in many environmental, biophysical, and technological processes. Resolving the internal…
