| Abstract: | The He(I) photoelectron spectrum of β-hydroxyethyldimethylamine N-oxide shows the degenerate pair of N-oxide ionic states to be shifted by 0.49 eV to higher ionization potential, relative to the non-hydrogen bonded system. The two bands remain nearly degenerate. The ionization of the hydroxy lone pair is shifted by > 0.6 eV to lower ionization potential. INDO calculations for the corresponding ionic configurations of a model system (NH3O + H2O) are compared with the experimental observations. |
