FTIR spectrometer ThermoFisher Nicolet iS5

Contact: Pablo Forjanes

Location: C359

The IR spectrometer is used for fast routine IR spectra acquisition in the 4000-400 cm^-1 range with a maximum resolution of 0.9 cm^-1, although in practice higher resolution than 4 cm^-1 is seldom necessary. IR spectra can be measured on both liquid and solid samples. The measurements are usually performed using the diamond attenuated total reflectance (ATR) accessory that allows to obtain a spectra in a few minutes with no sample preparation of very small (<1 mg) sample quantities. Measurements of KBr pellets or similar samples in transmission geometry are also possible. List of accessories available:

• iD7 diamond ATR (most commonly used)
• iD1 transmission
• iD1 in-situ probe with Si ATR tip
• iD Foundation multi-bounce ATR with either ZnSe or Ge prism
