Abstract

Positively and negatively charged duster ions were produced from methanol and ethanol samples under low temperature secondary ion mass spectrometric conditions. Neat alcohol dusters [M(n)·H+], [M(n)-H]- and mixed alcohol-water duster sets [M(n)·(H2O)(m)·H+] and [M(n)·(H2O)(m)-H]- sets were recorded as the most prominent peaks in the spectra. Clusters composed of up to 30 molecules have been observed. Distributions of these duster series, and also some satellite ion dusters observed with lower abundances, are discussed.
