Question

What are the limitations of Infrared Spectroscopy ?

Answer 1

The study of the relationship between matter and electromagnetic radiation as a result of the radiation's wavelength or frequency is known as spectroscopy.The method of spectroscopy is used to research the properties of atoms and molecules. The vast number of wavelengths released by these devices allows researchers to study their structures in depth, including ground and excited state electron configurations.

Complete answer:
The study of infrared light interacting with a molecule is known as Infrared Spectroscopy.Absorption, emission, and reflection can all be measured to determine this.This approach is primarily used in organic and inorganic chemistry. Chemists use it to identify functional groups of molecules. One of the most popular and commonly used spectroscopic techniques is Infrared (IR) Spectroscopy. IR Spectroscopy has many advantages and uses, but they also have limitations.

The limitations of IR spectroscopy are:
-IR spectroscopy fails to give details on the relative positions of a molecule’s functional groups.
-It is impossible to determine a substance's molecular weight using IR spectroscopy.
-Non-adherence with Beer's law of complexity spectra is a frequent occurrence.
-Spectra narrowness is used to calculate absorbance based on slit width and wavelength setting.

Note: The theory of IR spectroscopy is based on the idea that molecules absorb particular frequencies of light that are typical of the molecule's composition. The energies are determined by the form of the molecular surfaces, the resulting vibronic coupling, and the mass of the atoms.
