IR/Raman |
The center of the IR/Raman laboratory is a Nicolet Magna 850 FTIR
spectrometer with Raman module.
- The FT-IR 850 Bench is equipped with specific sets of beamsplitter/detectors:
- ability to work in the
- MIR (400 - 4,000 cm-1) --- framework basicity
- NIR (4,000 - 12,500 cm-1) --- defect SiOH
- FIR (10 - 400 cm-1) --- cations translations
- cells allowing in-situ measurements both in
transmission and in reflection
- Diffuse Reflectance (DRIFTS) --- highly opaque or weakly
absorbing samples
- Photoacoustic (PAS) --- opaque samples
- Attenuated Total Reflectance (ATR) --- optically dense
materails
- Raman Module:
- Organic/Inorganic interactions in hybrid materials
- Organics trapped in layered and porous framework
- Experiments to check the validity of simulated results
(Force Field, etc.)
- Sample Tubes: 5mm O.D. NMR tubes are the easiest to use. The dimensions
should be as follows:
- Min/Max Tube Height = 4 cm and 5 cm, respectively
- Minimum Sample Height = 2 cm
However, if limited sample is available, then 1.5 cm spacers
can be used and only 0.5 cm of sample is required
- Continuum IR Microscope: Surface Mapping, i.e. correlation
of molecular information with sample position, to be acquired.
- Regulations and Procedures
for Using IR or Raman.
The IR/Raman laboratory is equipped with a vacuum line and other
gas lines (He, N2, O2, Air, etc.) which allows simple sample preparation
and the ability to perform in-situ studies on the IR/Raman
spectrometer.
