Abstract

The high-energy pentagonal pinch mode of C₆₀ is known to soften under high incident laser irradiance in an oxygen-free environment. We have studied this phenomenon in C₆₀ films, single crystals, and solutions in CS₂. Our Raman, optical absorption, and EPR data indicate that the softened Raman peak is related to very long lived states in C₆₀. The experiments are consistent with the recently proposed photoinduced polymerization of C₆₀ and also suggest the presence of C₆₀ anions in the photoexcited material.
