Abstract
For the problem of the reflection and transmission of monochromatic radiation incident on a moving inhomogeneity of medium characteristics, the regimes for transforming a real frequency into a complex one are discovered. This makes it possible to develop spectroscopy of complex frequencies for absorbing media or near the regime of total internal reflection. It is also shown that, taking into account the complex frequencies, Doppler frequency shifts are found unambiguously if initial conditions for radiation and medium are specified.
