Notes:
Resonance excitation profiles have been obtained for cobalt phthalecyanine at both room temperature and 10 K using a compressed disc of silver and the phthalocyanine. Low-frequency vibrations are shown to be influenced mainly by displacements on the bonding nitrogen, but high-frequency vibrations show a more complex pattern with some evidence that the vibrations v3 and v28 depend on Cα displacements. By comparison with copper, there appears to be a greater degree of scattering from 0-0 and 0-1 transitions and there is a shift towards increase 0-0 scattering in the sharper low-temperature profiles. It is concluded that a distortion, dynamic at room temperature and static at low temperature, plays a key role in determining the relative scattering and this distortion is larger for copper phthalocyanine than for cobalt phthalocyanine.
