excitointiaallonpituuden
Excitointiaallonpituuden, often translated as excitation wavelength, refers to the specific wavelength of light or other electromagnetic radiation that is absorbed by a molecule or atom, causing it to transition from a lower energy state to a higher energy, excited state. This absorption process is fundamental to many phenomena in physics and chemistry, including spectroscopy, fluorescence, and photochemical reactions.
When a photon with energy precisely matching the energy difference between two electronic or vibrational energy
In techniques like fluorescence spectroscopy, a sample is illuminated with light at a specific excitation wavelength.
