What is quantum transition for the uv-vis absorption?
Quantum transition for the UV-VIS absorption refers to taking the electron transitions associated with visible and ultraviolet.
When a molecule absorbs UV radiation what does it cause?
When a molecule absorbs UV, it decomposes. Ozone also does the same.
Why you get broad peak in UV spectroscopy instead of sharp peak?
UV-visible absorption spectroscopy probes electronic transitions due to electronic excited states, where as absorption of IR radiation excites molecular vibrations and no electronic excited states. However, UV-visible radiation can also excite the molecular vibrations as well, and so what is observed is the superposition of the electronic absorption in addition to the vibrational absorption spectra. IR spectra are broadened by molecular rotations, which are caused by the absorption of lower energy microwave radiation (and rotational spectra can be extremely sharp). If the species you are probing are atoms only, than they do not have any vibrations (because there are no bonds) and so the UV-visible spectra of atoms is very sharp.
The warm temperature observed in the stratosphere is primarily because of the absorption of ultraviolet radiation by ozone?
The source of the warmth of the stratosphere is the absorption of UV radiation by ozone, hence reduced ozone leads to cooling.
What type amino acid absorbed UV radiation?
Tryptophan is an amino acid that absorbs UV radiation. It has a strong absorption peak in the UV range, around 280 nanometers, which makes it useful for studying protein structure and interactions using techniques such as UV spectroscopy.

In which layers of the atmosphere does the temperature increase with increasing height?
The stratosphere is where the temperature increases with height. This is due to absorption of UV radiation by atmospheric ozone.

What is uv absorption?
UV absorption is done by ozone. It is present as ozone layer.
Which substance present in the atmosphere is responsible for the absorption of solar radiation with a wavelength less than 242 nm?
Oxygen is responsible for the absorption of solar radiation with a wavelength less than 242nm. UV radiation splits oxygen into atoms and the atoms combine with other oxygen molecules to form ozone. Generally, all multi-atom?æ compounds are capable of absorbing UV radiation when the wavelength is short.
What type of organic compounds show UV absorption bands?
Aromatic compounds, conjugated dienes, and compounds with extensive pi-electron systems often show UV absorption bands. These compounds have delocalized electrons that can undergo electronic transitions when exposed to ultraviolet light, leading to absorption of UV radiation.
Which are more energetic photons of UV-A radiation or photons of UV-B radiation?
UV-B.
What effect does the ozone's absorption of ultraviolet radiation have on the stratosphere?
The ozone absorbs the UV rays. These UV rays are very much harmful for life on earth. Thus ozone protects us from these fatal rays.
How do UV and radiation relate?
UV is a type of radiation. It is fatal for life on earth.
