The polystyrene matrices are identifiable in FTIR thanks to the bands relating to the bonds present within the macromolecule:
- Strips around 3100-3000 cm-1 from streching = aromatic CH
- Stripe around 1640 cm-1 after streching C = C
- Band around 697 cm-1 from the skeleton -CH close to the aromatic nucleus ...
