Mode Assignment of Sulfur α-S8 by Polarized Raman and FTIR Studies at Low Temperatures

“…The ω 1 (stretch at 475 cm -1 ) and ω 7 (stretch at 475 cm -1 )as Raman active modes in the isolated moleculegive rise to a strong broad Raman spectrum in which we could only identify the a g component. This is in accordance with the calculated Raman intensities, which are, for the a g components of all three stretching modes, much larger than for the other components. The IR spectrum of these two modes is mainly influenced by the very strong absorption due to the ω 5 mode, and only the b 1u component of ω 7 is well resolved.…”

“…The overall intensity pattern of the internal Raman active modes (Figure a) is nicely modeled by ref , besides the ω 10 and ω 1 /ω 5 /ω 7 regions.…”
