Learning Objectives

Students should:
$be able to use data from high resolution ¹H NMR spectroscopy to: i predict the different types of proton present in a molecule, given values of chemical shift, δ ii relate relative peak areas, or ratio numbers of protons, to the relative numbers of ¹H atoms in different environments iii deduce the splitting patterns of adjacent, non-equivalent protons using the (n+1) rule and hence suggest the possible structures for a molecule iv predict the chemical shifts and splitting patterns of the ¹H atoms in a given molecule$
