Reliable integrals require: ‐ homogenous sample ‐ a homogeneous NMR sample ‐ sufficient relaxation time (d1) - usually not a problem in 1H NMR, but in 19F NMR we. - Solutions to summary problems are available online to prevent students from instantly getting to the answers before they have worked hard to solve the problems. It provides a basic introduction to the theory and instrumentation for each technique. Here is an example of a typical 1H‐NMR spectroscopy problem when the molecular formula is given, and the steps you take in order to solve it. The multiplicity of some signals is noted.
