I am a beginner at orbitals. It seemed interesting to me while studying p orbitals that the texts don't suggest that the orbitals are rigid relative to the nucleus.
But I thought mathematically these rotations would not be possible to know because the wave function of the orbitals only tell about the probability. Until this:(Simple rotation of an atomic orbital wavefunction)( I didn't understand it as I don't know the mathematics; I am trying)
So, is it possible for orbitals to rotate relative to the nucleus? If yes, what validates it; if no, what disallows it?
