Water can absorb infrared (IR) radiation due to its molecular vibrations, which correspond to the energy of IR photons. These vibrations involve bending and stretching of the O-H bonds, allowing water molecules to interact with IR light effectively. In contrast, visible light has higher energy photons that do not match the energy levels associated with the vibrational transitions of water, resulting in minimal absorption in that region. Thus, water is transparent to visible light while being a strong absorber in the IR region.
What else can I help you with?
Can be visible or infrared?
I can't think of anything that could be those two and nothing but those two. Electronic structure spectroscopy is generally in the UV/Visible band, but I suppose it could extend down into the near IR. Vibrational spectroscopy (with rotational fine structure) is in the IR, but doesn't make it up into the visible region.
Can infrared radiation be stopped by materials?
Yes, infrared radiation can be blocked by materials that are opaque to it, such as metal foils, dense fabrics, and certain plastics. These materials absorb or reflect the infrared radiation, preventing it from passing through.
What happens when water absorbs an IR photon?
When water absorbs an infrared (IR) photon, the molecular vibrations of the water molecules increase as they absorb the energy from the photon. This increase in vibrational energy causes the water molecules to move more vigorously and increase in temperature.
Does IR have UV Rays?
Infrared (IR) radiation is distinct from ultraviolet (UV) radiation as they are found at opposite ends of the electromagnetic spectrum. IR radiation has longer wavelengths than visible light, while UV radiation has shorter wavelengths than visible light.
What are the other regions of spectroscopy aside from the visible region?
Other regions of spectroscopy include ultraviolet (UV), infrared (IR), microwave, radio, X-ray, and gamma-ray spectroscopy. Each region provides information about different aspects of a molecule's structure and behavior. UV spectroscopy is commonly used to study electronic transitions, while IR spectroscopy is utilized for molecular vibrations.
Explain glass cell cannot be used for IR region?
Glass absorb IR.
What does water absorb?
IR Radiation otherwise known as Infrared Radiation or heat energy

Why water cannot be used as solvent in IR spectroscopy?
Water has strong absorption bands in the IR region, which can interfere with the absorption bands of the sample being analyzed. This background noise can make it difficult to accurately interpret the IR spectrum of the sample. Additionally, water tends to have a broad and featureless absorption band in the typical IR region, making it a poor solvent for IR spectroscopy.
Is IR rays visible to eyes?
No.
Can infrared radiation be stopped by materials?
Yes, infrared radiation can be blocked by materials that are opaque to it, such as metal foils, dense fabrics, and certain plastics. These materials absorb or reflect the infrared radiation, preventing it from passing through.
Why are salt crystal cells used in IR spectroscopy instead of glass or quartz cells?
Glass and quartz cells have high absorbency's of photons in the IR range, these are better for analyses in the UV/Vis region. Salt crystal cells, however, typically absorb very little IR radiation, making them optimal for IR spec.
What happens when water absorbs an IR photon?
When water absorbs an infrared (IR) photon, the molecular vibrations of the water molecules increase as they absorb the energy from the photon. This increase in vibrational energy causes the water molecules to move more vigorously and increase in temperature.
What is the shortest region of the electromagnetic spectum?
Visible region is the shortest region in the electromagnetic spectrum. Please see the attached picture. It is the shortest defined region. However if you mean wavelength, the further you go on the UV side, the shorter the wavelength. If you are talking about frequence, frequency and wavelength are inversely proportional, so it would be furthest to the IR side. The question is not about the shorter wavelength or less frequency. It is about the region covered in the whole spectrum. So visible with VIBGYOR having wavelength starting from 350 nm to 750 nm will be the visible region where as other regions such as UV and IR would have a larger range.
Which region of ir spectrum is reffered to as fingerprint region?
1700cm
Does IR have UV Rays?

Why you can see the ir led through camera?
Most digital camera sensors are sensitive to a small range of IR, as well as visible light.
