The influence of addition of Zn on band parameters of Zn_{x}Cd_{y}Hg_{1-x-y}Te solid solution at different temperatures (4.2-200 K) was investigated. The cyclotron resonance at 4.2 K and magnetophonon reso­nance at 77-200 K were used to determine band structure parameters. The temperature dependence of band structure parameters (energy gap, effec­tive mass of electron) for the composition of series of epilayers (x varied in 0.08-0.20 range and y - 0.07-0.12) was obtained. It is found that band struc­ture parameters for some compositions (for example x = 0.17, y = 0.08) are almost independent from temperature and equal: γ₁^{L}= 19.55, γ₂^{L} = γ₃^{L} = 8.5, K^{L} = 6.48, F = -0.5, E_{g} = 0.35 eV, E_{p} = 17.9 eV. The effective mass of electrons was found to be greater with addition of Zn while the effective mass of heavy holes is left unchanged.
