Abstract:
The multiphoton ionization of acetone-water clusters were detected at 355 nm laser wavelength by using the time of flight mass spectrometer (TOF-MS). The experiments show that all products are protonated. Three main products such as (CH3COCH3)n-(H2O)n−2H+, (CH3COCH3)n-(H2O)n−1 H+ and (CH3COCH3)n−(H2O)nH+ are concluded from the results. In order to study the equilibrium structures of the (CH3COCH3)n−(H2O)n−2H+, the ab-initio calculation is used on them. The experiment is even done when the volume rate of acetone to water is 1∶2.
