Title:INFRARED SPECTROSCOPY OF [(H2S)2(X)1]+ (X = WATER, METHANOL, AND ETHANOL): INFLUENCE OF THE MICROSOLVATION ON THE HEMIBOND

Abstract:Changes of the excess charge accommodation motif in hemibonded hydrogen sulfide by microsolvation are studied by infrared spectroscopy of the [(H${_2}$S)${_2}$(X)${_1}$]$^{+}$ (X = water, methanol, and ethanol) clusters. While the hemibond in the (H${_2}$S)${_2}$$^{+}$ ion core is stable to the microhydration by a single water molecule, it is broken by the proton transfer with the microsolvation by a single methanol or ethanol molecule. Hetero hemibond formation between hydrogen sulfide and these solvent molecules is not observed. On the other hand, the H${_3}$S$^{+}$ ion core in the protonated H$^{+}$ (H${_2}$S)${_2}$ cluster is switched to H${_3}$O$^{+}$ ion core by the microhydration with a single water molecule, even though the proton affinity of water is lower than that of hydrogen sulfide.
