description: The given work is devoted to coherent spectroscopy of thin films in the time domain, its relevance and features, optical properties of thin films, details of the mathematical model for describing and calculating the optical and electrical parameters of a film with organometallic perovskite CH3NH3PbI3 and its application. Spectroscopy in the time domain is carried out using the radiation of terahertz pulses generated by a femtosecond laser through an n-InAs emitter. THz radiation was detected using a crystal ZnTe orientation (110) and a thickness of 1 mm by electro-optical gating. In addition, the main components of the experimental setup for recording waveform of a terahertz signal transmitted through the sample, as well as its transmission spectrum are described in detail. The calculation of the refractive and extinction coefficient, as well as the complex conductivity and permittivity, is described. The spectral dependences of these quantities in the terahertz region were obtained.
