Abstract: 

We present resonance Raman measurements of crystalline trishomocubane and diamantane dimers containing a C=C double bond. Raman spectra were recorded with excitation energies
between 2.33 eV and 5.42 eV. The strongest enhancement is observed for
the C=C stretch vibration and a bending mode involving the two carbon atoms of the C=C bond, corresponding to the B_2g wagging mode of ethylene. This is associated with the localization of the π-HOMO and LUMO and the elongation of the C=C bond length and a pyramidalization of the two sp²-hybridized carbon atoms at the optical excitation. The observed Raman resonance
energies of the trishomocubane and diamantane dimers are significantly
lower than the HOMO-LUMO gaps of the corresponding unmodified
diamondoids.
