Abstract
A consistent description of temperature modulated differential scannin g calorimeter (TM-DSC) curves based on irreversible thermodynamics is presented within the scope of the validity of the linear response appr oximation. Both time-independent and time-dependent processes are incl uded. For time-dependent (linear) processes, the heat how rate is conn ected to the convolution integral. This results in a generalized heat capacity which is frequency dependent and, on principle, a complex fun ction of it.
