Excitation Energy-Dependent Decay Dynamics of the S₁ State of N‑Methyl-2-pyridone

, 2023
The UV-induced decay dynamics of N-methyl-2-pyridone is investigated using a femtosecond time-resolved photoelectron spectroscopy method. Irradiation in the wavelength range of 339.3–258.9 nm prepares N-methyl-2-pyridone molecules with very different ...
