N2  - The far-infrared spectra of AsS, As2S3, As4Se3, and As2Se3 are reported for the range 15-400 cm-1. For As4S3 molecules, of symmetry C3v, strong bands at 370 cm-1 and 340 cm-1 arise from symmetric As-S stretching frequencies of symmetry class A1 and a strong band at 176 cm-1 arises from a S-4s-S bending mode of degenerate class E. For As2Se3, bands in the region 90-130 cm-1 are identified as Se-As-Se bending modes and bands between 200 and 280 cm-1 are due to As-Se stretching modes.
