How To Determine Nuclear Spin Quantum Number

This is kind of a question for those who are studying quantum physics, but still since this concept is important in NMR, I am guessing some of you will know this. Thanks.

You need to know smth about nuclear structure. I don't really know anything about it, but you don't need it for NMR since the Spins for the relevant nuclei are known and can be found in tables.

I am sorry to disappoint you, but to answer this question is not something you can easily calculate on a piece of paper.

13C has a spin of -1/2, not 1.

To my understanding, an odd number of proton+neutron results in a half-integer spin. The details of the organisation within the nucleus (which is unknown presently) changes only integer amounts of the spin.
