More Book Details

Description of the Book:

Van der Waals clusters of Mo(CO)6 generated in the free jet expansion of a pulsed beam of seeded helium are subjected to multiphoton ionization and the product ions analyzed by quadrupole mass spectrometry. Oxy-molybdenum and dio-oxy-molybdenum ions are observed to be produced with hig efficiency. This behavior is in striking contrast to that of metal carbonyl monomers and covalently bound cluster carbonyls, which undergo ligand loss prior to ionization. The observed photochemistry is ascribed to reactions between a photo-produced molybdenum atom and the ligands of neighboring Mo (CO)6 solvent molecules within the van der Waals cluster. Keywords: Carbonyl compounds; Molybdenum
