A fractional (or stretched) time exponential, F(1) = exp[ -(t/F)"], where O<cr< 1, T a time constant, is proposed as the modulation function for vibrational band-narrowing in locally structured, amorphous media. It leads to physically sounder modulation times than current, pure exponential models, y
