Quantification of Unimolecular Photoreaction Kinetics: Determination of Quantum Yields and Development of Actinometers—The Photodegradation Case of Cardiovascular Drug Nisoldipine

Figure 5

A linear relationship between the overall rate-constant of NIS photodegradation (obtained as the fitting parameter of the kinetic data with (1)) and the photokinetic factor of the photoproduct (calculated using (3)) when irradiating various concentrations of NIS solutions (0.39–2.06 × 10−5 M) at 320 nm and observing at 390 nm.
