DDT is, technically, dichloro-diphenyl-trichloroethane, a chemical compound that was produced in a Scottish laboratory in 1873 by Othmar Zeidler. In 1939, Paul Mueller, working in Switzerland, discovered that DDT was in fact an insecticide, and was awarded the Nobel Peace prize for his work. During...

An introduction to NMR spectroscopy and its utility in science
By: Sam Blazer
Every chemist must know the principles behind Nuclear Magnetic Resonance. Nuclear magnetic resonance is a technique which utilizes the properties of the nucleus of the atom, in order to decode the structure of the molecule. It is thus an important tool for chemists who would...
