| dienophile | a cmpd containing a double bond (consisting fo one or two C, N, or O atoms) that can react with a conjugated diene to give a Diels-Alder adduct |
| Diels-Alder adduct | a cyclohexene resulting from the cycloaddition reaction of a diene and a dienophile |
| cycloaddition reaction | a reaction in which two reactants add together in a single step to form a cyclic product; the best known of these is the Diels-Alder rxn |
| pericyclic rxn | takes place in a single step, without intermeds, and involves a cyclic redistribution of bonding electrons |
| UV spectroscopy | a cmpd is irradiated with UV or visible radiation, absorption of which causes electrons to change form a lower electronic level to a higher one. UV spectroscopy is particularly valuable for det the extent of conjugation in organic molecules containing pi bonds |
| absorbance (A) | a quantative measure fo the extent to which a cmpd absorbs radiation of a particular wavelength. A = log Io/O, where Io is the incident radiation, and I is the transmitted |
