Vibrational Spectra of C<sub>60</sub>·C<sub>8</sub>H<sub>8</sub> and C<sub>70</sub>·C<sub>8</sub>H<sub>8</sub> in the Rotor-stator and Polymer Phases

Vibrational Spectra of C<sub>60</sub>·C<sub>8</sub>H<sub>8</sub> and C<sub>70</sub>·C<sub>8</sub>H<sub>8</sub> in the Rotor-stator and Polymer Phases

C60·C8H8 and C70·C8H8 are prototypes of rotor-stator cocrystals. We present infrared and Raman spectra of these materials and show how the rotor-stator nature is reflected in their vibrational properties. We measured the vibrational spectra of the polymer phases poly(C60C8H8) and poly(C70C8H8) resulting from a solid-state reaction occurring on heating. On …
