This paper describes the investigation of nonlinear behavior in a solution of C60. A Q-switched Nd:YAG laser operating at 532 nm was used to look at the change of absorbance during the time of the pulse. The open literature has suggested that scattering may provide part of the nonlinear process found in C60 solutions and this problem is addressed in this paper. Nonlinear scattering in toluene, a carbon suspension in toluene, and C60 solution in toluene was investigated between 0 and 90 degrees. The C60 solution produced as much nonlinear scattering as the toluene on its own.
