In Search of Microscopic Evidence for Molecular Level Negative Thermal Expansion in Fullerenes

S. Brown, J. Cao, J. L. Musfeldt +5

We report the high-resolution far infrared vibrational properties of C60 and endohedral Kr@C60 fullerene as a function of temperature. Anomalous softening of the F1u(1) mode (526 c…
