When a molecule absorbs a photon, its energy increases and the electrons in the molecule are excited to higher energy levels. This can lead to changes in the molecular structure or bond vibrations. In some cases, the molecule may undergo a chemical reaction or emit a photon in a process known as fluorescence or phosphorescence.

A pigment absorbs a photon only if the energy of the photon is?
greater than or equal to the energy gap between its ground and excited states.
When matter absorbs a photon what is the relationship between the energy of the matter before and after the absorpion and the frequency and the wavelength of the radiation absorbed?
When matter absorbs a photon, the energy of the matter increases by an amount equal to the energy of the absorbed photon. The frequency and wavelength of the absorbed radiation depend on the energy of the photon and are inversely related - higher energy photons have higher frequencies and shorter wavelengths.
What happens in the photo system 2 protein when its hit by a photon of light?
When a photon of light hits the photosystem II protein, it excites an electron within the chlorophyll molecule, causing it to jump to a higher energy state and leave the chlorophyll molecule. This electron is then passed down an electron transport chain to generate ATP and NADPH for use in the light-dependent reactions of photosynthesis.
What is the source of an emitted photon?
An emitted photon is typically generated when an electron transitions from a higher energy level to a lower energy level within an atom or molecule. This transition releases energy in the form of a photon.
If you make the electron jump downward then return it to the outer ring what do you notice about the photon released or absorbed?
When an electron jumps downward to a lower energy state in an atom, it releases energy in the form of a photon which is emitted. When the electron returns to the outer ring, it absorbs energy in the form of a photon. The energy of the photon absorbed is equal to the energy of the photon released during the downward jump.
What happens when carbon dioxide absorbs an IR photon?
The molecule vibrate
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.
When a molecule absorbs a photon one of the electron is raised in what state?
When a molecule absorbs a photon, an electron is raised from its ground state to an excited state. This leads to an increase in the electron's energy level, causing the molecule to become temporarily unstable before returning back to its ground state through various relaxation processes.
What happens when a molecule absorbs a photon of infrared radiation?
When a molecule absorbs a photon of infrared radiation, its internal energy increases, causing the molecule to vibrate more rapidly. This vibration can lead to changes in the molecule's structure or interactions with nearby molecules, which can have various effects such as heating up the molecule or triggering chemical reactions.
What gets excited when chlorophyll absorbs a photon?
electrons
When a pigment molecule absorbs a photon one of its electrons?
When a pigment molecule absorbs a photon, one of its electrons gets excited to a higher energy state. This causes a change in the molecule's electronic structure, leading to various downstream effects such as triggering a chemical reaction in photosynthesis or generating an electrical signal in vision.
What happens when a photon hits a chlorophyll molecule?
When a photon hits a chlorophyll molecule, it excites an electron within the molecule to a higher energy state. This energized electron is then passed along a chain of molecules in the photosystem to eventually drive the process of photosynthesis, converting light energy into chemical energy.
What is one possible molecule formed by photo ionization?
One possible molecule formed by photoionization is a molecular ion, such as H2+ (hydrogen ion). This process occurs when a molecule absorbs a photon with enough energy to remove an electron, resulting in the formation of a positively charged ion.
A pigment absorbs a photon only if the energy of the photon is?
greater than or equal to the energy gap between its ground and excited states.
When going up an energy level what happens?
When an electron moves up an energy level, it absorbs energy in the form of a photon. This causes the electron to jump to a higher energy level and become excited. The electron will eventually return to a lower energy level by emitting a photon of light.
What is a possible result of an atom that absorbs sufficient energy?
The atom may emit a photon.
When matter absorbs a photon what is the relationship between the energy of the matter before and after the absorpion and the frequency and the wavelength of the radiation absorbed?
When matter absorbs a photon, the energy of the matter increases by an amount equal to the energy of the absorbed photon. The frequency and wavelength of the absorbed radiation depend on the energy of the photon and are inversely related - higher energy photons have higher frequencies and shorter wavelengths.
