Forbidden Lines: A Window into Atomic Transitions

Imagine a shadowy world where certain transitions are forbidden, where electrons dance around the atom's nucleus, eager to leap but held back by invisible barriers. These barriers are what we call forbidden lines.

Forbidden lines arise from metastable states, where electrons linger in an excited state for a relatively long time, like a child perched on the edge of a diving board, hesitant to take the plunge. But just as the child eventually leaps, the electron eventually transitions to a lower energy level, releasing a photon of light.

These transitions are forbidden because they violate certain selection rules, which govern the allowed energy level transitions. Yet, these lines are indeed observed in emission spectra, revealing the hidden world of these metastable states.

The presence of forbidden lines in emission spectra provides invaluable insights into the physics of gases and plasmas. They allow us to probe the subtle interactions between electrons and atoms, unraveling the secrets of these enigmatic states.
