A peak in the IR spectrum represents the presence of a specific bond or functional group that absorbs infrared light at characteristic frequencies.

The mid-infrared region is typically used to identify functional groups due to the characteristic absorption bands.

IR spectroscopy detects vibrational modes of molecules, which occur when bonds stretch or bend.

A chromophore is the part of a molecule that is responsible for its color and absorbs light in the UV-Vis region.

The Beer-Lambert Law relates the absorbance of light to the concentration of a solution, allowing for concentration determination.

UV-Vis spectroscopy provides rapid and quantitative analysis, making it a preferred method for many applications.

A blank is used to account for the absorbance of the solvent, ensuring that only the sample's absorbance is measured.

A blank sample is used to provide a reference for baseline correction, ensuring that only the absorbance due to the analyte is measured.

UV-Vis spectroscopy typically measures wavelengths in the range of 200-800 nm, covering both ultraviolet and visible light.

Solid samples in IR spectroscopy are often prepared by forming KBr pellets to allow for proper transmission of IR light.

A Fourier-transform infrared spectrometer (FTIR) is commonly used for IR spectroscopy to obtain high-resolution spectra.

UV-Vis spectroscopy is commonly used to quantify concentrations of colored solutions based on their absorbance.
