Abstract
Fullerene C-60 exhibits a continuous and reversible A(g)(2) mode softe ning from 1469 to 1459 cm(-1), which is linear with laser power up to 21.9 kW/cm(2) for C-60 crystals under vacuum. Model calculations takin g into account the temperature distribution that is induced by the Gau ssian intensity profile of the laser beam reproduce the measured frequ ency shifts. A thermal conductivity of microcrystalline fullerene of 0 .27(+/- 0.03) W/mK is derived from this numerical analysis.
