  • Ultraviolet-visible (UV-VIS) spectroscopy
  • Analytical method based on transitions between electronic energy states in molecules. Useful in studying conjugated systems such as polyenes
  • Unimolecular
  • Describing a step in a reaction mechanism in which only one particle undergoes a chemical change at the transition state
  • Unsaturated hydrocarbon
  • A hydrocarbon that can undergo addition reactions; that is, one that contains multiple bonds
  • Unshared pair
  • in a Lewis structure, two valence electrons of an atom that are in the same orbital and not shared with any other atom.
  • Upfield
  • The high-field region of an NMR spectrum. A signal that is upfield with respect to another lies to its right on the spectrum
  • Uronic acids
  • Carbohydrates that have an aldelhyde function at one end of their carbon chain and a carboxylic acid group at the other
