Jablonski diagram

A Jablonski diagram is a visual representation used in chemistry and physics to illustrate the electronic states of molecules and how they interact with light. It shows energy levels of electronic states, excited states, and processes like absorption and emission of light, as well as transitions between these states. In essence, it helps explain phenomena like fluorescence and phosphorescence by detailing how molecules absorb energy and then release it as light. The diagram features vertical lines for energy levels and arrows to indicate transitions, making complex interactions easier to understand.
