I genuinely believe it's ...

Molecular orbital theory describes the distribution of electrons in molecules in much the same way that the distribution of electrons in atoms is described using atomic orbitals. Using quantum mechanics, the behavior of an electron in a molecule is still described by a wave function, Ψ, analogous to the behavior in an atom.Just like electrons around isolated atoms, electrons around atoms in ...

Whereas molecular geometry considers only the atoms. In absence of a lone pair, both the geometries are the same for any compound. Below is the 3D view of the geometry of the SO2 molecule. SO2 Geometry. Now let’s learn the last topic of this article, the molecular orbital diagram of SO2. SO2 Molecular Orbital Diagram

Of these options, F⁺ has the electron configuration [He]2s²2p⁴, which has unpaired electrons in the 2p orbital. Therefore, F⁺ will be paramagnetic and therefore attracted to a magnetic field. Use the MO diagram (below) to calculate the bond order for I₂. The d electron count is a chemistry formalism used to describe the electron configuration of the valence electrons of a transition metal center in a coordination complex. The d electron count is an effective way to understand the geometry and reactivity of transition metal complexes. The formalism has been incorporated into the two major models used to describe coordination … In the following diagram, two 1s atomic orbitals combine to give a sigma (σ) bonding (low energy) molecular orbital and a second higher energy MO referred to as an antibonding orbital. The bonding MO is occupied by two electrons of opposite spin, the result being a covalent bond. Bonding molecular orbitals are formed by in-phase combinations of atomic wave functions, and electrons in these orbitals stabilize a molecule. Antibonding molecular orbitals result from out-of-phase combinations of atomic wave functions and electrons in these orbitals make a molecule less stable. This made me think about two problems:

I am a graduate student in Chemistry in an Inorganic class. We have touched on Tanabe-Sugano diagrams in class, but did not go into deep explanation. The homework problems I have been given use these diagrams, but I am not sure how to use them. What I understand: These diagrams show the allowed transitions for both high and low spin complexes. I thought that term symbols were used to read these diagrams, but the E, T, and A designations look more like molecular orbital labels. Somehow, the de...

Various methods (Hartree-Fock methods, semi-empirical methods, Density Functional Theory, Molecular Mechanics) used to optimize a molecule structure feature the same basic approach but differ in the mathematical approximations used. The geometry optimization procedure calculates the energy at an initial geometry of a molecule and then proceeds to search a new geometry with a lower energy ...

As stated previously, continuous bands of energy are formed due to the combinations of molecular orbitals close in energy. Of course, due to the mass amounts of different molecular orbital mixings, bands of varying energy will form. The difference between these band energies is known as the band gap, as indicated in Figure 2. Figure 2.

Molecular Orbital theory is a concept of quantum mechanics that attempts to explain the chemical bonding inside any molecule. In this theory, we get to know that valence electrons can be shared amongst all constituent atoms and atomic orbitals from different atoms combine to form molecular orbitals ( MOs ).

Cross posted from chem help so forgive me if for some reason you’re seeing this twice now. I’m working through a problem set for one of my classes and so far it’s had me make the SALCs and molecular orbital diagram for NH3. Now it’s asking me to go from constructing the MO diagram to identifying the ground electronic state of the molecule. I’m guessing what I need is some kind of wave function to describe the population of each orbital in the ground state. But I’m not sure how to get there fro...

Hello, I'm a chemistry student with a personal interest in programming and I have, for my personal project, tried to make a crude program for calculations using the Hückel theory of molecular orbitals. From the mathematical standpoint, the problem boils down to filling up a giant matrix with x's on the main diagonal and up to three 1's in every row/column. Then you have to take the determinant of the said matrix and solve the generated polynomial. The solutions are then displayed both as a list ...

Hi /r/Chempros. Have you ever shed blood and tears on writing a script, only to find after a few weeks that something really similar had already been done?

I have, and after a quick exchange with our dear mod /u/wildfyr I've decided to post this thread. #Scope I would like for it to be a location ...

While learning about ferrocene I've come across this molecular orbital diagram. What particularly confused me is the nature of the a'1g orbital. My professor taught that a'1g and e2g are considered HOMO bonding orbitals, but this MO diagram clearly shows the a'1g as an MO with antibonding character.

A diagram is a symbolic representation of information using visualization techniques. Diagrams have been used since prehistoric times on walls of caves, but became more prevalent during the Enlightenment. Sometimes, the technique uses a three-dimensional visualization which is then projected onto a two-dimensional surface. The word graph is sometimes used as a synonym …

A machine learning algorithm has identified an antibiotic that kills E. coli and many other disease-causing bacteria, including some strains that are resistant to all known antibiotics. To test it, mice were infected on purpose with A. baumannii and C. difficile and the antibiotic cleared the mice of both infections. "The computer model, which can screen more than a hundred million chemical compounds in a matter of days, is designed to pick out potential antibiotics that kill bacteria using dif...
