We performed Reverse Monte Carlo analysis (RMCA) to study amorphous structure of a heterofullerene, CN by using pulsed neutron powder diffraction data. The scattering function S(Q) shows that the structure is amorphous, while the atomic pair distribution function (PDF) shows that the local structure is similar to that of C. Obtained structures strongly depend on the initial models. Problems for this RMCA method are discussed.
