Photoionisation mass measurements on oxygen and acetylene molecules have been made in the wavelength region from 1100 to 400 A by using synchrotron radiation as a light source. Photoionisation spectra in oxygen are obtained for the molecular ion O2+ and for the fragment ion O+, and in acetylene are obtained for the molecular ion C2H2+ and for fragment ions C2H+, C2+, CH2+ and CH+. To assign the spectral structures of C2H2+, ab initio calculations have been performed for excitation from the second (3I´g) and third (2I´u) outer molecular orbitals. In the molecular ion spectra of these molecules, several broad structures are observed besides sharp structures due to autoionisation from rydberg states. The broad fetures are ...
