Three-pulse infrared photon echo spectroscopy has been used to determine the correlation function of fluctuations vibrational frequencies OCN- and SCN- in methanol. The functions antisymmetric stretching modes for these two ions are fitted with a double exponential time constants around 100 fs 4 ps. amplitude is found be greater than that OCN-. We discuss difference spectral diffusion processes between
