WebAug 11, 2024 · 2 Answers. A single hydrogen atom has only one electron. Thus, it is in an (electronic) doublet state and there are no singlet or triplet states. The two states of the doublet are different in energy due to spin-orbit coupling. Basically, the electron can spin in the same direction as it is orbiting the nucleus or in the opposite direction. WebSep 21, 2024 · Because a sample of hydrogen contains a large number of atoms, the intensity of the various lines in a line spectrum depends on the number of atoms in each excited state.
