I'm also not sure what you mean... Bound electrons (in an orbital) can only have 1 of 2 quantum "spin" states - which is in relation to the nucleus and/or the magnetic field. Up or down. With the spin-up electron having a slightly higher or lower energy level then the spin-down electron (depending on other factors).
