摘要：

Fast time-resolved infrared spectroscopy (TRIR) is used to probe the photochemistry of W(CO)5(4-acetylpyridine) inn-heptane. Visible irradiation (510nm) 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 pp between the lowest MLCT state and the 3LF state, approximately 4000 cm-1.
