Why is a singlet state called singlet and a triplet state called triplet?
An electron can have a spin quantum number of $+\frac12$ or $-\frac12$. For a system that exists as a singlet, all spins are paired and the total spin for the system is $S=0$. If we have a single electron, $S=\frac12$. If we have a triplet system with 2 unpaired electrons, $S=1$.

Triplet state - Wikipedia
In quantum mechanics, a triplet state, or spin triplet, is the quantum state of an object such as an electron, atom, or molecule, having a quantum spin S = 1. It has three allowed values of the spin's projection along a given axis mS = −1, 0, or +1, giving the name "triplet".

2022年1月29日 · Such an orbital-symmetric and spin-antisymmetric state is called the singlet. The origin of this term becomes clear from the analysis of the opposite (orbital-antisymmetric and spin-symmetric) case: \[\psi\left(\mathbf{r}_{2}, …
Singlet state - Wikipedia
In quantum mechanics, a singlet state usually refers to a system in which all electrons are paired. The term 'singlet' originally meant a linked set of particles whose net angular momentum is zero, that is, whose overall spin quantum number . As a result, there is only one spectral line of a singlet state. In contrast, a doublet state contains one unpaired electron and shows splitting of spectral li…
