摘要：
A general susceptibility fitting function is here introduced to the mechanical relaxation research community. As an example the function is tested on high quality shear modulus data from the literature. Using this equation we find that time-temperature-superposition holds for the main relaxation of tripropylene glycol. The advantages compared to using a commonly used curve fitting function arc discussed.
