✦ Synopsis

Mass spectra of (HzO),, (CH3OH), and (C~HSOH), (n < 4) were measured by varying the source conditions for the supersonic expansions. The dependences have revealed that (H20);, (CHsOH);, m/z 77 ion from ethanol dimer and (M2H -18)+ ions (M =Cl$OH, C2HsOH) from the trimers are useful for detection of the corresponding neutral clusters without significant contamination by fragmentation from other clusters.
