摘要：

The photoacoustic (PA) spectra of undoped C-60 and C-70 crystals have been measured as a function of temperature, 35 similar to 300 K, and chopping frequency. At room temperature, PA signal edges associated with abrupt increases are found near 1.8 eV. With a decrease in temperature; a tail appears near the lower energy side of the PA signal edge for both C-60 and C-70, where structures reflecting the molecular vibronic modes are superposed. Solid state effects are observed clearly for C-60 as a discontinuous shift of the PA edge by similar to 0.02 eV at 260 K corresponding to structural transformation and as a relaxation effect on change of molecular configuration.
