I don't want to know the shape. I want to know the physical relation between the shape and the spin number. How does spin implies the shape? Or how does nuclear shape implies the spin number?
I'm beginner in NMR studies and now I'm studying quadrupole interaction. In this case, spins larger than 1/2 have a non-spherical charge distribution and this asymmetry interacts with external electric fields.
But the question is: What is the relation between the nuclear shape (or charge...
