Investigation and modeling of evolution of $\mathrm{C}_{60}$/NMP solution UV-Vis spectra

The kinetics for the dissolution of fullerene $\mathrm{C}_{60}$ in $\mathrm{N}$-methyl-$2$-pyrrolidone (NMP) solvent are investigated through measurements of the stirring speed and temperature dependence of the UV-Vis absorption spectra. We develop a model for the kinetics of simultaneously occurring processes in the solution, employing a system of simple kinetic equations and obtain the corresponding parameters dependence on preparation conditions. The obtained results will allow one in the future to consider these effects when modeling the slow growth kinetics of large clusters in $\mathrm{C}_{60}$/NMP solutions.
