You cannot classify vibrations as "this is due to excitation / this is not". Every vibration is an excitation relative to the ground state.Mendelevskij said:Can the vibration be the same for them if they are not excited (do not vibrate due to excitation)
Vibrations in a solution refer to the movement or oscillation of molecules or particles within a liquid. These vibrations can be caused by external forces such as sound waves or internal forces such as thermal energy.
Vibrations can affect a solution in various ways. They can help mix or disperse particles within the liquid, aid in chemical reactions, or even cause changes in the physical properties of the solution such as its viscosity.
The frequency of vibrations in a solution can be affected by factors such as temperature, pressure, and the concentration of particles in the solution. Additionally, different types of molecules or particles can have different natural frequencies of vibration.
Studying vibrations in a solution can provide insights into the behavior and properties of liquids at the molecular level. This knowledge can be applied in various fields such as chemistry, engineering, and medicine.
Vibrations in a solution can be measured using techniques such as spectroscopy, which analyzes the absorption or emission of light by the solution, or rheology, which measures the stress and strain of the solution under vibration.
