✦ Synopsis

Positively and negatively charged cluster ions were produced from methanol and ethanol samples under low temperature secondary ion mass spectrometric conditions. Neat alcohol clusters [M n . H + ], [M n -H] -and mixed alcohol-water cluster sets [M n . (H 2 O) m . H + ] and [M n . (H 2 O) 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 cluster series, and also some satellite ion clusters observed with lower abundances, are discussed.

Negative-ion low-temperature fast-atom bombardment mass spectrometry (LT-FAB-MS) is applied to monomeric and dimeric [60]fullerene compounds. LT-FAB mass spectra of C 60 , C 60 O 1-3 , C 119 , C 120 , C 120 O, C 120 O 2 (B) and C 120 OS exhibit clear molecular ion peaks and a moderate level of fragm
