在UV激发下，溶液中的M（CO）6（M = Cr、Mo或W）物种失去一个CO配体，并且溶剂分子占据空位。 这些光化学反应进行了研究，使用瞬态宽带红外吸收技术与390 fs的时间分辨率。 这些反应的进展，包括损失的M（CO）6反应物，外观的溶剂化的M（CO）5（正己烷）的产品和振动能量分布和松弛的产品，监测通过红外吸收的变化由CO配体附近2000 cm-1。
Following UV excitation, M(CO)6 (M = Cr, Mo or W) species in solution lose one CO ligand, and a solvent molecule occupies the vacant site. These photochemical reactions are studied using a transient broadband IR absorption technique with 390 fs time resolution. The progress of these reactions, including loss of the M(CO)6 reactant, appearance of a solvated M(CO)5(n-hexane) product and vibrational energy distribution and relaxation of the product, is monitored through changes in infrared absorption by the CO ligands near 2000 cm-1.
