Abstract : The document is largely comprised of abstracts of papers presented at the conference. The application of photoelectron spectroscopy dealt with were particularly those of species identification and qualitative analysis through the characteristic shapes and shifts of the spectral lines of atoms in different chemical environments. The technique of photoelectron spectroscopy with its high sensitivity and wide energy ranges, provides a very useful means of examining some of the fundamental ideas in molecular orbital theory. Koopman's theorem is found to be fairly well obeyed in most cases; orbital assignments of the experimental spectra fit in well with ideas of bonding and antibonding orbitals, and charge shifts can be well correlated with electro-negativities and bond polarity calculations. Selection rules can be checked experimentally, and models of the vibronic structure of complex molecules can be put to a searching test.
