We report the results of Raman, infrared, and inelastic neutron scattering investigations of the vibrational spectrum of the complex p-tert-butylcalix8arene1:1fullerene, a system with almost isolated C60 molecules confined inside neutral cages. All the internal optical-active modes of the C60 guest have been identified, and further modes which can be attributed to C60 intramolecular vibrations appear in the neutron scattering function. A comparison with the vibrational spectrum of empty p-tert-butylcalix8arene indicates that the hostguest interaction is very weak. As solid-state effects are also practically suppressed, the investigated complex gives the unique opportunity to study almost free fullerene balls confined in the solid state.

Abstract
We report the results of Raman, infrared, and inelastic neutron scattering investigations of the vibrational spectrum of the complex p-tert-butylcalix8arene1:1fullerene, a system with almost isolated C60 molecules confined inside neutral cages. All the internal optical-active modes of the C60 guest have been identified, and further modes which can be attributed to C60 intramolecular vibrations appear in the neutron scattering function. A comparison with the vibrational spectrum of empty p-tert-butylcalix8arene indicates that the hostguest interaction is very weak. As solid-state effects are also practically suppressed, the investigated complex gives the unique opportunity to study almost free fullerene balls confined in the solid state.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
