Structural Determination
Learning outcomes - after studying this topic, you should be able to:
- identify the molecular ion, base peak and daughter ions in a mass spectrum
- recognize that a fragmentation pattern in a mass spectrum can lead to structural information
- recognize the isotope distribution characteristic or bromine and chlorine containing compounds in a mass spectrum
- use the information that IR and UV-visible spectra provide to aid in the determination of structures
- identify the number and type of hydrogen environments in a molecule and predict the the number of signals in a 1H NMR spectrum
- predict the number of hydrogen atoms in each environment from the size of the signals in a 1H NMR spectrum
- predict the number of hydrogen atoms on neighbouring atoms from the multiplicity of the signals in a 1H NMR spectrum
- determine the structure of a simple compound from spectroscopic data
