The Solvation of Ca²⁺ with Gas Phase Clusters of Alcohol Molecules.

ABSTRACT: A comprehensive examination of how the identity of an alcohol molecule can change the behavior of a solvated, alkaline earth dication has been undertaken. The metal dication of Ca²⁺ has been clustered with a range of different alcohols to form [Ca(ROH)_n]²⁺ complexes, where n lies in the range 2-20. Following collisional activation via electron capture from nitrogen gas, complexes for n in the range 2-6 exhibit a switch in reaction product as a function of n. For low values, solvated CaOH⁺ is the dominant fragment, but as n increases beyond 4, this is displaced by the appearance of solvated CaOR⁺. A separate study of unimolecular metastable decay by [Ca(ROH)_n]²⁺ complexes found evidence of charge separation to form
