Raman spectra of TlIn(S1–xSex)2 (0 ≤ x ≤ 0.25) single crystals in the frequency range 16–400 cm−1 were studied at T = 30 K in the Z(XX+XY)Z¯ configuration. The experimental Raman spectra of TlIn(S1-xSex)2 single crystals were analyzed by multi-peak simulation by Lorentzian contours, enabling the peak frequencies, halfwidths and intensities to be determined. Their compositional dependences were studied...
