What is FTIR and why it is used? 5 Key Points to Understand

FTIR (Fourier-transform infrared) spectroscopy is an analytical technique used to determine the molecular structure of a sample.

This method involves the use of infrared light to analyze the chemical bonds within a molecule.

When infrared light encounters a sample, each type of bond in the molecule absorbs a specific wavelength of light, which is then converted into vibrational energy.

By analyzing the wavelengths of light absorbed, chemists can identify the different types of bonds present in an unknown molecule.

What is FTIR and why it is used? 5 Key Points to Understand

1. Basic Principle of FTIR Spectroscopy

FTIR spectroscopy uses infrared light to analyze the chemical bonds within a molecule.

Each type of bond in the molecule absorbs a specific wavelength of light, which is then converted into vibrational energy.

2. Sample Preparation Techniques

One common method of preparing a sample for FTIR analysis involves diluting it in a material like potassium bromide (KBr) and then using a hydraulic press to condense it into a solid pellet.

This method is effective for analyzing powder samples and has become widely used with the advent of FTIR technology.

3. Alternative Measurement Techniques

Other measurement techniques such as the diffuse reflection method and attenuated total reflection (ATR) method are also employed in FTIR spectroscopy.

The choice of method depends on the form of the sample, with each technique offering unique advantages for different types of samples.

4. Applications of FTIR Spectroscopy

FTIR spectroscopy is a powerful tool for chemists and researchers, providing fast and accurate analysis of molecular structures.

Its ability to identify different types of bonds in a molecule makes it an essential technique in fields such as materials science, pharmaceuticals, and environmental analysis.

5. Advantages of FTIR Technology

FTIR spectroscopy allows for the detailed analysis of molecular structures without the need for extensive sample preparation.

This makes it a versatile and efficient tool for various scientific applications.
