Each substance has known specific maximum of absorption. Comparing spectra substances can be identified.
A spectrophotometer is an instrument commonly used to measure absorption spectra of samples. Microscopes do not typically have the capability to measure absorption spectra like a spectrophotometer can.
Aniline shows absorption peaks in the ultraviolet region around 210-220 nm due to its benzene ring structure. The spectrum can be used for identification and quantification purposes in analytical chemistry. The exact UV spectrum of aniline may vary depending on its concentration and solvent used.
UV absorption is the process by which molecules absorb ultraviolet (UV) light and transition to higher energy states. This absorption of UV light causes electronic transitions in the molecules, leading to distinct absorption spectra that can be used to identify and quantify the presence of specific compounds. UV absorption spectroscopy is a common technique used in analytical chemistry and biochemistry for characterizing compounds based on their UV absorption properties.
Emission spectra can be used to identify components in a mixture by analyzing the unique patterns of light emitted by each component when subjected to energy. By comparing these patterns to known spectra of elements or compounds, scientists can determine the composition of the mixture. Each component will emit specific wavelengths of light that can be matched to known standards, aiding in identification.
refers to the quantal absorption of photons over a range of wavelengths of light used for excitation; different molecules tend to absorb different amounts of radiation over a range of wholly different wavelengths. This would give rise to a spectrum which can be plotted.
The extinction spectra is actually the measurement of light absorption in different mediums. This spectra is used in chemistry and biochemistry.

The absorption spectra of phloroglucinol show peaks around 220-230 nm due to its aromatic structure containing benzene rings and hydroxyl groups. This compound absorbs light in the UV region and is commonly used in chemical analysis and spectrophotometry.

Spectrophotometers pieces of equipment used to take in light and break it down to its spectral components. The sun or a lamp can be used to provide the light for an experiment.

Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
An absorption spectrum is a graph that shows how much light is absorbed by a substance at different wavelengths. It appears as a series of peaks and valleys. Scientists use absorption spectra to identify the chemical composition of a substance, study its properties, and understand its behavior in various conditions.
