Yes, an FTIR (Fourier-transform infrared spectroscopy) can be used in an inorganic project for analyzing various compounds, identifying functional groups, and characterizing materials based on their infrared spectra. This technique is particularly useful for studying inorganic compounds due to its sensitivity to metal-ligand vibrations and can provide valuable information on the composition and structure of the samples.
A Fourier-transform infrared (FTIR) spectrometer is the instrument used to perform FTIR spectroscopy. It works by measuring the absorption of infrared radiation by a sample. It consists of an interferometer and a detector to measure the signal.
An interferometer in FTIR (Fourier-transform infrared spectroscopy) is a device that splits and recombines a beam of infrared light, leading to the generation of an interferogram. This interferogram is then mathematically transformed into a spectrum, providing information about the sample's chemical composition. The interferometer is a crucial component in FTIR spectrometers for producing high-quality spectra.
Lasers are used in FTIR spectroscopy to provide a monochromatic and intense light source, improving spectral resolution and sensitivity. This enhances the ability to detect specific functional groups and chemical bonds in the sample. Additionally, lasers offer stability and coherence, which are essential for precise measurements in FTIR analysis.
Crushing a ceramic capacitor for FTIR analysis can be done by placing the capacitor in a mortar and pestle and grinding it into a fine powder. Ensure that the ceramic material is completely broken down to achieve a homogeneous sample for FTIR analysis. Wear appropriate protective gear to prevent inhalation of particles during the crushing process.
The principle of FTIR is based on the fact that bonds and groups of bonds vibrate at characteristic frequencies. A molecule that is exposed to infrared rays absorbs infrared energy at frequencies which are characteristic to that molecule. In a molecule, the differences of charges in the electric fields of its atoms produce the dipole moment of the molecule. Molecules with a dipole moment allow infrared photons to interact with the molecule causing excitation to higher vibrational states. Diatomic molecules do not have a dipole moment since the electric fields of their atoms are equal. During FTIR analysis, a spot on the specimen is subjected to a modulated IR beam. The specimen's transmittance and reflectance of the infrared rays at different frequencies is translated into an IR absorption plot consisting of reverse peaks. The resulting FTIR spectral pattern is then analyzed and matched with known signatures of identified materials in the FTIR library.

It is used but not after wavelengths higher than 15 micrometres.
FTIR instruments have distinct advantages over dispersive spectrometers: 1. Better speed and sensitivity. 2. Internal laser reference. The use of a helium neon laser as the internal reference in many FTIR systems provides an automatic calibration. 3. Increased optical throughput. 4. Simpler mechanical design. 5. Elimination of stray light and emission contributions.
The main instrumental difference between IR (infrared spectroscopy) and FTIR (Fourier-transform infrared spectroscopy) is the way in which the spectra are collected. In IR, the instrument measures the absorption of infrared radiation directly, while in FTIR, the instrument measures the interference pattern created when an infrared beam passes through a sample and a reference. FTIR is generally more sensitive and provides better resolution compared to traditional IR spectroscopy.
