What type of information is collected using FTIR fourier transform infrared spectroscopy?
What type of information is collected using FTIR fourier transform infrared spectroscopy?
Morphology of nanomaterial
Absorption of functional group
Geometry of particles
Particle size
Solution
1. Morphology of nanomaterial
- FTIR does not provide information about morphology (shape, structure) of nanomaterials. Techniques like SEM or TEM are used for this. This is incorrect.
2. Absorption of functional group
- FTIR identifies functional groups by detecting characteristic absorption bands in the infrared region, such as those for $-\mathrm{OH},-\mathrm{CH},-\mathrm{NH},-\mathrm{CO}$, etc. This is correct.
3. Geometry of particles
- FTIR does not give information about particle geometry (e.g., spherical or cubic shapes). This is incorrect.
4. Particle size
- FTIR cannot determine particle size. Techniques like DLS (Dynamic Light Scattering) or electron microscopy are used for this. This is incorrect.
