摘要：
The vacuum ultraviolet photoionization and photodissociation of 1, 2-dimethoxyethane have been studied by using synchrotron radiation. The ionization potential of 1, 2-dimethoxyethane is determined to be (9.33 +/- 0.04) eV. The appearance potentials of the fragments CH3OCH2CH3+ and CH3OCH2+ are found at (9.83 +/- 0.05) and (9.99 +/- 0.05) eV, respectively. According to the experimental results and the energies calculated by B3LYP/6-31 + G (d) theory, the main possible channels of the photodissociation have been analyzed. The enthalpies of formation of the ions CH3OCH2CH2OCH3+, CH3OCH2CH3+ and CH3OCH2+, and the bond energies of D-0(CH3OCH2-CH2OCH3) and D-0(CH3OCH2-CH2OCH3) have been evaluated.
