Unlike in Feynman diagram
Unlike in Feynman diagrams, wavy arrows, which can be labeled as internal conversions or intersystem crossings, in these represent radiationless transitions. They are equivalent in many ways to state diagrams and use horizontal lines to represent molecular electronic states. They also contain straight arrows, which typically represent phosphorescence, fluorescence, or photon absorption. Identify these diagrams named after a Polish scientist.
