The method of reflection against a sample and short in &electric time domain spectroscopy (TDS) is d&usse& It is shown how, by a proper choice of sample lengths, the method can be used to reach even the high-frequency end of the spectxum accessible by TDS. Results for test measurements on benzyl alcohol and chlorobenzene are given

A theoretical analysis is presented of the lumped capacitance method and its small capacitance approximation using a Debye dielectric permittivity relation and low frequency conductivity. The influence of fringing fields are discussed. The results of the small capacitance method are compared with t
k simple physical picture is given of Fellncr-Feldegg's thin celi method in time dokin spectsoscapy. From this pic!ure an accurate analytical relstion is derived for the total reflection coefficient.
## Some variants of the treatment of results obtamed by the lumped-capacitance method are discussed. The applicability of different algonthms of the numerical Fourier-Laplace transformation is anlysed.
