The Q band in absorption spectra refers to the region where electronic transitions occur between closely spaced energy levels in molecules or complexes. It typically corresponds to longer wavelengths in the visible or near-infrared range, and is often associated with changes in the vibrational and rotational motion of the molecules. The intensity and shape of the Q band can provide information about the structure and electronic properties of the molecules.

How absorption spectra can be used in the identification of unknowns?
Each substance has known specific maximum of absorption. Comparing spectra substances can be identified.
What microscope can plot an absorption spectrum of the item under examination?
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.
How can forensic scientists use emission line spectra and absorption spectra?
Forensic scientists can use emission line spectra and absorption spectra to analyze trace evidence, such as glass fragments or paint chips, found at a crime scene. By comparing the spectra of the collected samples with reference spectra, scientists can identify the chemical composition of the evidence and link it to potential sources or suspects.
Why do stellar spectra have absorption lines?
Need a different, better answer.
What are the factors of which width of absorption spectra of complexes depend?
The width of absorption spectra of complexes depends on factors such as the ligand field strength, the nature of the metal ion, the coordination geometry, and the electronic structure of the complex. These factors affect the energy levels of the metal d orbitals and influence the electronic transitions that give rise to absorption bands in the spectra.

How Many types of Infrared Spectra?
There are three main types of infrared spectra: absorption spectra, emission spectra, and reflection spectra. Absorption spectra are produced when a material absorbs infrared energy, emission spectra are produced when a material emits infrared radiation, and reflection spectra result from the reflection of infrared radiation off a material.
What is extinction spectra?
The extinction spectra is actually the measurement of light absorption in different mediums. This spectra is used in chemistry and biochemistry.

What are the similarities between emission and absorption spectra?
The lines are at the same frequencies
Which type of spectrum do most stars have?
Most stars have absorption spectra. In other words, stars possess thin outer layers that allow light to pass through. These layers produce what are called absorption lines. This means the light from the sun and stars are absorption spectra.
