Abstract

We have studied the protonated ether—(H~2~O)~n~ (n = 1–3) complexes containing tetrahydrofuran, dimethyl, diethyl, dibutyl, and butylmethyl ethers using a flowing afterglow triple‐quadrupole mass spectrometer. Collision‐induced dissociation, CID, of all clusters with n = 1, 2 shows sequential water loss. The n = 3 cluster of dimethyl ether shows sequential water loss, while all other ether clusters display selective product formation. The CID spectra are interpreted based on known energetics, and theoretical studies of the dimethyl and diethyl ether systems. Copyright © 2006 John Wiley & Sons, Ltd.

The potential energy surfaces for the proton transfer processes in H+(H20), with n = 2 -11 have been studied using the semiempirical AM^ method. Two model systems were adopted branched and linear systems. The branched system showed a tendency to form a bulk cluster, while the linear system showed a

Cluster size distribution and collision-induced dissociation (CID) studies of protonated methanol and protonated methanol-water clusters yield information on the structure and energetics of such ions. Ions were formed at atmospheric pressure in a corona discharge source, and were subjected to CID in
