Triplet-State Energy of the Photostabilizer Tinuvin P

Electron‐energy‐loss spectroscopy shows that the lowest triplet level of the photostabilizer molecule Tinuvin P (= 2‐(2′‐hydroxy‐5′‐methylphenyl)benzotriazole) is at ca. 3.0 eV. Tinuvin P acts as a photostable inner filter rather than as a quencher of excited impurity sites.
