Abstract
Fast time-resolved infrared spectroscopy (TRIR) is used to probe the photochemistry of W(CO)5(4-acetylpyridine) in n-heptane. Visible irradiation (510 nm) populates the lowest MLCT state, which is monitored by TRIR. Subsequent dissociation to W(CO)5⋯n-heptane, via equilibrium with the 3LF state, is also followed. On UV irradiation (308 nm), the LF state is populated directly and W(CO)5⋯n-heptane appears immediately. With 510-nm irradiation, the yield of W(CO)5⋯n-heptane as a function of temperature is measured to give a value for the energy gap between the lowest MLCT state and the 3LF state, −4000 cm−1.
