The temperature dependence of the vibrational modes in the diphosphides ZnP₂ and CdP₂ has been studied by employing IR reflectance spectroscopy within the 4…300 K temperature range in the polarized radiation. It has been demonstrated that decreasing the bond distance in the phosphorus chain at low temperatures causes an additional amount of anharmonicity of the corresponding modes, which is manifested in more pronounced temperature dependences of their frequencies and damping coefficients.
