Raman and infrared phonons in tetragonal ZnP2 and CdP2 crystals: a density functional study.
2020
Lattice dynamic properties of the tetragonal modification of ZnP2 and CdP2 crystals (space group P41212, no. 92) are calculated within the density functional theory. Theoretical results are shown to compare favorably with available Raman scattering and infrared reflection/transmission experimental data, which allows assignment of Raman-and infrared-active modes to the specific lattice eigenmodes. It is confirmed that several distinct features of vibrational spectra of these compounds steam from the presence of four phosphorous spiraling chains within crystallographic unit cell.
