    Description / Table of Contents: Cyclooctadienynes  -  Highly Strained C8H8-HydrocarbonsApplying the MNDO-method the conformations with lowest energy of the isomeric cyclooctadienynes 1-4 are calculated. The geometrical ring strains Eg can be evaluated from the enthalpies of formation ΔHf in relation to the cyclooctatrienes 5 and 6. UV, IR (Raman) and 13C NMR spectra serve as an experimental probe for the ring strain.
    Notes: Mit Hilfe der MNDO-Methode werden die energieärmsten Konformationen der vier strukturisomeren Cyclooctadienine 1-4 berechnet. Aus ihren Bildungswärmen ΔHf können durch Bezug zu den Cyclooctatrienen 5 und 6 die geometrischen Ringspannungen Eg abgeschätzt werden. Als experimentelle Sonde für die Ringspannung dienen die UV-, IR (Raman)- und 13C-NMR-Spektren.
