CHEM 344 Thin Layer Chromatography
TLC, one phase is a mobile liquid solvent phase and the other phase is a stationary solid phase with a high surface area. The stationary phase normally consists of a finely divided adsorbent, silica (SiO 2) or alumina (Al 2O 3) powder, used in the form of a thin layer (about 0.25 mm thick) on a supporting material.

Assigning the 1H-NMR Signals of Aromatic Ring 1H-atoms
www2.chem.wisc.eduthe signals in the aromatic region. 3) Model compound An often over-looked and under-utilized method of assigning the signals in the 1H-NMR region is by comparison to known molecules. Let us assume that the 1H-NMR spectrum of o-isopropylaniline is not available in any database. It is very similar to at least three common compounds (benzene,
