dc.description.abstract
A state-of-the-art gas electron diffraction (GED) apparatus has been reassembled in
the school of chemistry at the University of Edinburgh. This combines molecularbeam
and telefocus-electron-gun technologies and the alignment of the electron
beam produced by the latter has been discussed. A new custom-made CCD detector
has also been installed and electron diffraction patterns for a few small molecules
have been recorded. In analogy to the rotating sector in a conventional GED
apparatus, the new camera contains an optical filter and a procedure for its
calibration is outlined and followed step by step to produce an estimate of the filter
transmittance. The data have been shown to be of less than ideal quality and the
probable root of the problem is discussed.
GED refinements of two pairs of compounds (arachno-6,9-decaboranes, and a
covalent sulfonate and thiosulfonate) are presented, using data collected with the
conventional Edinburgh GED apparatus.
