We present the Raman scattering of single-crystal ZnIn2S4 as a functio
n of temperature in the range between 12 K and room temperature and an
analysis of the relative intensity changes for all the bands. Based o
n a group theoretical analysis using the different possible space grou
ps for this structure, the vibrational modes for the Raman spectra wer
e obtained and compared with the experimental data. A new space group
is proposed for the crystal structure for this semiconductor.
