%X The vacuum ultraviolet (VUV) photoionization and dissociative photoionization of methyl acrylate have been studied at the photon energy range of 9.0~15.5 eV by using synchrotron radiation and a reflection time-of-flight mass spectrometer (TOF-MS). The photoionization mass spectra and photoionization efficiency (PIE) curves for fragment ions m/e=86(C4H6O+2), 85(C4H5O+2), 59(C2H3O+2), 58(C3H6O+), 55(C3H3O+), 42(C3H+6), 31(CH3O+), 27(C2H+3), and 15(CH+3) from methyl acrylate have been measured. In addition, the energetics of the dissociative photoionization species have been calculated using ab initio Gaussian-3 (G3) programs. The calculated ionization energies (IEs) and appearance energies (AEs) are in good agreement with the experimental data. Moreover, the main dissociative photoionization channels, simple bond cleavage reactions, are proposed.
