The vibrational spectroscopy of M@C82 (M=La, Y):
Far-infrared, Raman, and neutron inelastic scattering results — •S. Lebedkin1, B. Renker1, R. Heid1, and H. Schober2 — 1Forschungszentrum Karlsruhe, INFP, Postfach 3640, D-76021 Karlsruhe — 2Institut Laue-Langevin, BP 156, F-38042 Grenoble Cedex 9, France
We describe the procedure for producing tens of milligrams of metallofullerenes M@C82 (M=La, Y). This allows to study vibrational modes of M@C82 not only by Raman, but also by far-infrared and neutron inelastic scattering spectroscopy, requiring relatively large amount of a sample. Particular weight is put on the investigation of the excitation spectrum of the metal atom inside the carbon cage. Results from model calculations showing the principal grouping of vibrational modes and their dependance on the mass of the metal atom are presented.
