Is the spin linked to the third quantum number ?

In summary, the conversation is about the relationship between the third quantum number and spin. It is mentioned that they are linked by magnetism and the person asking the question wonders if an excited particle would have a different spin than a non-excited one. It is clarified that the third quantum number does not affect spin, at least not in the standard labels. The person asking the question apologizes for not being specific and thanks the other person for their answer.

Hi everyone,

As the title says, I was wondering if the third quantum number affects spin since they are both linked by magnetism. If not, will an excited particle have a different spin than a non-excited one ?

Thanks for your answer and sorry for the possible mistakes, I'm just a young french baguette.

Can you give more details, or a reference, to what particular scenario you are talking about?

No particular linkage, at least not if you're using the standard n,l,m,s labels for a bound electron, so that the third quantum number is m.

Yes I was talking about m, should've been more specific sorry. Thx for your answer.
 

1. What is spin in quantum mechanics?

Spin is an intrinsic property of particles in quantum mechanics that describes their angular momentum. It is a fundamental quantum number that determines how a particle interacts with magnetic fields and other particles.

2. How is spin related to the third quantum number?

In quantum mechanics, particles are described by a set of quantum numbers that determine their energy, angular momentum, and other properties. The third quantum number, also known as the magnetic quantum number, is directly related to the spin of a particle.

3. What is the significance of the third quantum number in spin?

The third quantum number, along with the other quantum numbers, helps to distinguish different energy states and orientations of particles. In the context of spin, it determines the direction of the particle's spin in relation to an external magnetic field.

4. Is the third quantum number the only factor that determines spin?

No, spin is also influenced by the type of particle and its interactions with other particles. For example, fermions have half-integer spin values, while bosons have integer spin values. The spin of a particle can also change when it interacts with other particles.

5. Can the spin of a particle be measured directly?

No, spin is a quantum property that cannot be directly measured. However, its effects can be observed and measured through experiments and calculations using the principles of quantum mechanics.
