Hole Transfer in Open Carbynes by Constantinos Simserides, Andreas Morphis, Konstantinos Lambropoulos

“…BLA in cumulenic cases is much smaller than in polyynic cases, so, although not strictly, the separation to cumulenes and polyynes, approximately, holds. Vibrational analysis confirms that for <i>N</i> even all cumulenes with coplanar methylene end groups are stable, for <i>N</i> odd all cumulenes with perpendicular methylene end groups are stable, and the number of hydrogen atoms at the end groups is clearly seen in all cumulenic and polyynic cases. …”
