What are t2g and eg in CFT?
In the crystal field theory (CFT), when the splitting of the d-orbital occurs, it gets divided into two parts.
The upper part with higher energy is the $\mathrm{e_g}$ and the lower part with lower ...

What is difference between T1g and T2g?
I know that the “$\mathrm{g}$” stands for symmetry of octahedral shape, but how are labels “1” and “2” given in $\mathrm{A_{1g}}$ and $\mathrm{A_{2g}}$ representations too…
Is it related to group ...

Molecular orbitals symmetry - states notation
I'm reading some papers and I'm repeatedly seeing the following notation of system states:
Could you, please, explain to me the meaning of it?
E.g. the state $B^2 \Sigma_u^+$ - I'm aware, that $\...

Multiplicity letter codes for large amount of states
Well, let's say we have a large amount of states computed (e.g. over 50), all with the same multiplicity.
So, our ground state can be $X^2\Sigma^+_g$ and we can continue with $B^2, C^2$ etc. as ...
