In Goto and Watarai, 2010, we can find a SERS study of Cysteamine subjected to magnetic pulling force. "The SC-CR bond of an alkanethiol chain, including cysteamine, can take two conformations: gauche and trans" (Goto & Watarai, 2010, and references therein). "The two conformations are distinguishable from the Raman frequencies of C-S and C-C stretching vibrations". In Figure of Goto and Watarai work we can see the G band around 630 cm -1 and the T band at around 720 cm -1 .
