Question

Anal CH453 Exam 2 (version 1) ebruary 2, 2018 Protons and neutrons both have a spin quantum number of h. Protons form pairs with ot the nucleus with opposite spins and neutrons pair with other neutrons in spins. If the isotope of an element has even mass number and odd s 1. with other protons in same nucleus with opposine Momic number, what are the possible spin quantum numbers of the isotope? (10 pts) The spvn spin quantm number an hene Briefly explain why the NMR signals for carbon-13 are much weaker than those of proton. (10 ps)

Explanation / Answer

   The nuclear spin states can take any number, fraction or integer. The number is dependent on the three points
