How do hyperfine splits occur?

[tensus2000]

Hi Anyone,

This is my first post here and i have a bit of a quandry.

I'm doing some work related to hyperfine transition levels in Rubidium.
Ive been looking and asking but no-one can explain to me satisfactorly how hyperfine splits occur.
Mostly i get answers like " you should find out " , i can take that as meaning no-one yet knows or simply those i ask don't know.

I have the basics like electron spin and magnetic interactions etc but that's a bit wishy-washy.
I have to do a presentation on my project and I'm afraid someone who genuinely doesn't know might ask about how it occurs and i won't be able to give a satisfactory answer.

So any opinions or explanations would be mucho apreciado.

Cheers
Sean
