Another reference:

https://chemistry.stackexchange.com/questions/55209/orbitals-spdf-why-they-named-like-that/96351#96351

I found a poster reference where from memory he/she said:

- sharp
- pronounced
- diffuse
- foggy

which seems more to form but it disagrees with the literature.

As an aside, this reminds me of the River Runs Through It author, Norman McLean who described a small creek name "Wet A**" Creek which was later Indianified to Wetase Creek.

Your posts were very helpful, thanks. Are there any resources that show how they were derived from schrodinger's? Like, actual math? Thanks!

They aren't derived from math but from spectral line observation of elements and the results were then explained by quantum mechanics. The predictions of the Bohr model were wrong for some elements and other physicists adjusted the model by adding additional quantum numbers to bring it back into alignment with observation. Pauli's exclusion principle was the final one that allowed the new Bohr model to explain the lines.
