Nuclear Magnetic Resonance Spectroscopy - Physical Chemistry - Lecture Notes

Lecture Notes, Physical Chemistry

Post: December 24th, 2012
Description
Nuclear Magnetic Resonance Spectroscopy, Intrinsic Spin, Angular Momentum, Solutions for Nuclei, Spin Quantum Number, Property of Nucleus, Spin Eigenfunction, Protons and Neutrons. Before every lecture in Physical Chemistry, we received a lecture handout from lecturer. In end, we got all of them in soft form too. This is soft copy I am sharing with you. Enjoy.

Nuclear Magnetic Resonance Spectroscopy Nuclei have an intrinsic spin angular momentum just like electrons. The solutions for nuclei are structured in a similar manner: ˆ I 2  I ( I  1) 2 ˆ I z  mI  I I mI nuclear angular momentum vector spin quantum number (property of nucleus)   I , ( I  1) , ( I  2), ... ,  I spin eigenfunction ( , , ,...)  Exercise: Write out specific equations for the cases of I=1/2 and I=1. Use the vector model to interpret them. Discuss the relationship between I and the numbers of protons and neutrons present in an atom. In a magnetic field, the states are no longer degenerate in energy. There are different energy levels possible (two for nuclei that have spin ½) and transitions between them can be detected just like in other forms of spectroscopy. The transition energy depends on several things:  Strength of the applied field (Bo)  Magnetogyric ratio of nucleus (contained in the “g” ..
