CHROMATOGRAPHY  It is a method used for the separation, purification, and identification of a mixture of substances. It is useful when components of a mixture have similar physical and chemical properties and hence cannot be separated by other methods. Principle: It is based on the distribution of the components in a mixture between a stationary and a mobile phase. The stationary phase may be a column of adsorbent, a paper, a thin layer of adsorbent through which the mobile phase moves on. The mobile phase may be a liquid or gas. The principle of chromatographic separation is always adsorption (absorption of a constituent on the surface of the solid stationary phase) or partition (distribution of a constituent in between two liquid stationary phases). THEORY OF CHROMATOGRAPHY The separation takes place due to the differential migration of components which depends on the relative affinity towards the stationary and mobile phases.  The component which is less strongly held by th...

 NMR SPECTROSCOPY  NMR depends on the absorption of energy when the nucleus of an atom is excited from its lowest energy nuclear spin state to the next higher one.  The nuclear energy levels are produced by keeping nuclei in a magnetic field. The NMR spectrum is produced by EM radiation in the radio wave frequency region (60-500MHz).  NMR spectroscopy deals with nuclei having I=1/2. The spin quantum number (I) is related to the atomic number and mass number of the nucleus. Elements with either odd mass numbers or add atomic numbers have the property of nuclear spin. Radio waves are the lowest energy form of EM radiation. This energy is too small to vibrate, rotate or excite an atom or molecule. It is sufficient to influence the nuclear spin of the atoms of a molecule.  Principle of NMR The nucleus of an atom is positively charged, when it spins it develops a magnetic field and acts like a tiny bar magnet with a magnetic moment (µ) µ= I(I+1)1/2 h/2 π  The sp...
