Exploring Excited State: Spin and Photon Interactions

In summary, the conversation is about the relationship between excited state and spin. It is discussed that when an atom is exposed to light, the electron moves to a higher energy level, potentially causing a change in spin. The concept of spin conservation is also brought up, but it is clarified that total angular momentum of the system is actually conserved, not spin.

hi

i have a question about excited state:

let me say you have an atom and then you use light to get the electron to a higher energy level.

does this mean, that there is always a spin change, cause as far as i know the spin of a photon is 1.

but what happens if you have an electron with spin 1/2 and this electron absorbs a photon with spin 1. i know, that you cannot get an electron with spin 3/2, but on the other hand the spin is a conserved quantity, so how does this work out?

Spin is not a conserved quantity. Total angular momentum of the system is conserved.
 

Related to Exploring Excited State: Spin and Photon Interactions

1. What is the excited state of an atom?

The excited state of an atom is a state in which an electron has absorbed energy and moved to a higher energy level, or orbital, around the nucleus. This state is temporary and unstable, as the electron will eventually release the energy and return to its ground state.

2. How does spin affect excited state atoms?

Spin is an intrinsic property of particles, including electrons, that gives them a specific angular momentum. In excited state atoms, the spin of the electron can influence its behavior and interactions with other particles, such as photons.

3. What is the significance of photon interactions in excited state atoms?

Photon interactions are important in excited state atoms because they are responsible for the emission or absorption of energy that leads to the transition between energy levels. This allows scientists to study the energy levels and properties of atoms, as well as use them in various applications such as lasers and optical devices.

4. How do scientists explore excited state atoms?

Scientists use a variety of experimental techniques to study and explore excited state atoms. This can include using lasers to excite and manipulate the atoms, as well as using spectroscopy to analyze the emitted or absorbed photons and determine the energy levels and properties of the atom.

5. What are the real-world applications of understanding excited state atoms?

Understanding excited state atoms has numerous real-world applications, such as in the development of new technologies like lasers and optoelectronic devices. It also has implications in fields such as materials science, where the properties of excited state atoms can be used to improve the performance of materials. Additionally, knowledge of excited state atoms is crucial in fields like chemistry and biology, where it helps scientists understand chemical reactions and biological processes at the atomic level.
