Water vapor exists at a higher energy state than liquid water...but does that make a difference in the absorption bands? In other words, are the absorption bands of vapor and liquid water identical?
Thanks!
Thanks!
The infrared band is what I'm curious about. Also, my question was worded wrong...since liquid water has, on average, far more hydrogen bonds per molecule than water vapor, shouldn't there be an absorption difference? I would expect liquid water to absorb more strongly than vapor.Bystander said:Which absorption bands?
The absorption bands of liquid and vapor water refer to specific wavelengths of light that are absorbed by water molecules. These bands are caused by the vibrations of water molecules, which can be affected by factors like temperature and pressure.
The absorption bands of liquid and vapor water can affect the appearance of water by absorbing certain wavelengths of light, making the water appear to have a color or tint. This is why liquid water appears clear, while vapor water (clouds or fog) can appear white or gray due to the scattering of light by water droplets.
Studying the absorption bands of liquid and vapor water is important for understanding the properties and behavior of water, which is essential for life on Earth. It can also provide insights into environmental factors like weather and climate, as well as the detection of water on other planets.
The absorption bands of liquid and vapor water are measured using spectroscopy, a technique that involves passing light through a sample and measuring the amount of light absorbed at different wavelengths. This can provide information on the concentration of water molecules and the strength of the absorption bands.
Yes, the absorption bands of liquid and vapor water can change depending on factors like temperature, pressure, and the presence of other substances. This is why water can have different absorption patterns in different states (solid, liquid, vapor) and environments, and why scientists continue to study and characterize these changes.
