Kd. Kortmann et al., NEUTRON-DIFFRACTION STUDY OF END-FOR-END ORDERING IN COMMENSURATE SUBMONOLAYERS OF CARBON-MONOXIDE PHYSISORBED ON THE GRAPHITE BASAL-PLANE, Physica. B, Condensed matter, 234, 1997, pp. 167-169
The head-tail (dipolar) ordering in commensurate submonolayer films of
carbon monoxide adsorbed on graphite recently observed in heat-capaci
ty measurements for T < 5.18 K has been investigated by neutron diffra
ction. It will be shown that the experimental results are consistent w
ith an end-for-end ordered commensurate herringbone structure.
