Abstract

The use of H/D exchange technique for the structural investigation of serine octamer cations was discussed. Kinetics, pH dependence and dependence on entatiomeric composition of the H/D exchange process was studied. Electrospray and sonic spray spectra of the samples subjected to gas phase deuteration were recorded as a function of partial pressure of deuterating agent, enantiomeric composition, atmospheric interface temperature and pH of the introduced solution. The agreement between sonic spray and solution phase data and the significant difference from electrospray results suggested that one of the isomeric forms of the serine octamer was formed by the electrospray process.
