TEA CO2 Laser-Induced Infrared Multiphoton Dissociation of Zirconium Tetra-tert-Butoxide: Reaction Mechanism and Dissociation Products

Experiments of laser irradiation were performed to investigate the reaction mechanism of TEA CO2 laser-induced dissociation of zirconium tetra-tert-butoxide (Zr(t-OC4H9)4). The chemical structure of the dissociation product was analyzd by fast atom bombardment mass spectrometry (FAB-MS), infrared absorption spectroscopy, Raman spectroscopy, and 1H and 13C nuclear magnetic resonance (NMR) measurements. From the results, we surmise a reaction mechanism of the infrared multiphoton dissociation of Zr(t-OC4H9)4. The dissociation product is hydrolyzed in moist air to zirconium hydroxide (Zr(OH)4).
