Role and effects of the fast background contribution. The commonly observed fact that normalized NSE relaxation curves [S(Q, τ)/S(Q)] do not extrapolate to 1 if τ → 0 is caused by the presence of a very fast contribution to the scattering that only contributes at times shorter than the short-time limit of the NSE instrument. The red curves indicate the data after correction with the factor resulting from the amplitudes of slow (NSE) and fast dynamic contributions.
