## Abstract Polarized Raman spectroscopy was used to investigate the roomβtemperature phonon characteristics of a series of rareβearth arsenate (REAsO~4~, RE = Sm, Eu, Gd, Tb, Dy, Ho, Tm, Yb, and Lu) single crystals. The Raman data were interpreted in a systematic manner based on the known tetragon
