How do the spin-matrices change in systems without spherical symmetry?
The (non-relativistic) spin matrices of a free electron, with $z$ as the quantization axis, read:
$$
\boldsymbol{S}_{x}=\frac{\hbar}{2}\left[\begin{array}{ll}
0 & 1 \\
1 & 0
\end{array}\right],...

How to determine the angle between non-bonding electron pairs?
Is there a way to determine the angle between non-bonding electron pairs that aren't obvious? Take $\ce{H2S}$ for example:
The two non-bonding electron pairs would be at the yellow end of this ...

Does Bent's Rule only apply to molecules where there is hybridisation?
I would just like to ask if the pre-requisite for using Bent's Rule is that the bonding in the molecule involves hybridised orbitals.
I was thinking of why the bond angle in hydrogen sulfide (~ 92 ...

VSEPR Theory and Predicting Shapes of N2F2
I had asked a question on a IA Past Paper:
Predict the structure of $\ce{N2F2}$ using VSEPR Theory.
Now I'm not that strong at VSEPR theory. For the most part, I understand it when it involves a ...

Imposing particle number subspace on second quantized Hamiltonians
Here is my question:
Second-quantized Hamiltonians act on any state, regardless of how many electrons the state has. They are also block diagonal on different particle-number subspaces, as they ...

How does SOFC work?
The Solid Oxide Fuel Cell is a particular case in which an oxide is used as a conductor. Once i've heard that oxides usually aren't good conductors but it turned out that a lot of oxides are ...
