摘要：

The photochemistry of ketoprofen (KPF), 2-(3-benzoylphenyl)propionic acid, has been studied in aqueous solutions by time resolved (picosecond and nanosecond) spectroscopic techniques. Excited-state calculations were performed. The overall reactivity of the molecule was rationalized within a scheme in which the lowest triplet state can undergo intramolecular electron transfer and photoionization. The main pathway for the;formation of the decarboxylated photoproducts was shown to involve intramolecular electron transfer and to pass through triplet biradicals.
