Infrared absorption spectra of crystalline α‐P 4 S 3 are obtained at 80 and 275 K. Absorption features due to low frequency external modes are observed and are identified for the first time. Absorption due to internal molecular modes is compared with the data reported in previous works. α‐P 4 S 3 belongs to the centrosymmetric space group Pmnb(D 2h 16 ) and therefore none of the infrared active modes are Raman active. The present work is complementary to a recent Raman study on α‐P 4 S 3 .
