Homework Problem Set 2 Iverson CH310N Due Wednesday, February 4 (1 pt. each) Circle all the statements relating to the theory of NMR that are true. A magnetic field will cause charges to move. A magnetic field will not cause charges to move. Moving charge creates a magnetic field. Moving charge does not create a magnetic field. Electrons, neutrons, and protons are all charged. Neutrons and protons are both charged. Only electrons are charged. Both electrons and protons are charged. Atomic nuclei with an odd atomic mass or an odd atomic number have a quantum mechanical property called spin. The best way to the think about nuclear spin is as if nuclear postive charge (from the protons) were circulating within the nucleus, thereby creating a small magnetic field that can interact with a strong laboratory magnetic field. 1 H and 13 C nuclei have a spin quantum number of 2. 1 H and 13 C nuclei have a spin quantum number of 1. 1 H and 13 C nuclei have a spin quantum number of 1/2. The two spins states of a 1 H nucleus in a strong magnetic field are +1 and -1. The two spins states of a 1 H nucleus in a strong magnetic field are +1/2 and -1/2. The two spins states of a 1 H nucleus in a strong magnetic field are +2 and -2.
