| Popis: | Analytical description of the spectra of two coupled vibrational modes in the case of the homogeneous broadening of the interacting bands is proposed. Inter alia, the intrinsic overtone's intensity is taken into account in the course of the analysis of the spectral band shape of the Fermi doublet. General properties of the spectral band at different system parameters are examined. Some experimental spectra are interpreted with our formulas. It is shown that the common practice of decomposition of the observed band into Lorentzian constituents leads to improper values of the interaction parameters when the individual components of the Fermi doublet have different widths. |
