Raman and infrared spectra of rhombohedral selenium have been measured and the fundamental bands observed in these spectra are assigned by analogy to the S_6 ring molecule. Calculation of the normal mode vibration for the Se_6 ring using a modified Urey-Bradley force field confirms this assignment. Anomalous softening of the A_<1g> stretching mode relative to other modes and to the corresponding A_1 mode in the Se_8 ring was observed. This phenomenon is explained by the idea of interference of inter-molecular interaction with the intra-molecular bonding. Comparison of the observed spectra of rhombohedral selenium with those of other allotropes (α-monoclinic, trigonal, and amorphous selenium) suggests that Se_6 ring molecules may exist in amorphous selenium.
