# Raman Spectroscopy of NH$_4$MnCl$_3$ Crystal

### Abstract

The Raman spectra of the NH$_4$MnCl$_3$ crystal above and below the crystallographic phase transition are given for both the lattice and the ammonium modes. The results are discussed in terms of the structure of the crystal lattice and its influence on the symmetry of the ammonium ions.
