7 x 1 hour lessons

This module develops your skills in analytical chemistry. You’ll use data from a range of spectroscopic techniques—mass spectrometry, infrared (IR), and nuclear magnetic resonance (NMR)—to deduce molecular structures and confirm synthetic success.

​

By the end of this module you will be able to: • interpret mass spectra to determine molecular mass and fragmentation patterns • use IR spectra to identify functional groups • explain fingerprint regions in IR spectra and how they confirm identity • interpret ¹H and ¹³C NMR spectra, including splitting patterns and chemical shift • determine molecular structures from combined spectral data • understand the principles of chromatography (paper, TLC, GC) • use Rf values and retention times in identifying compounds • analyse and solve structure problems using all available data
