The directional characteristics of atomic orbital is explained in terms of the interaction between the resultant orbital angular momentum (or magnetic moment) and an externally applied magnetic field. A...
The molecular structure of protein and its function. Protein as a polymer of amino acids; how amino acid side-chains determine the structural configuration and chemical or enzymatic activity of protein.*
Concerned with spectroscopic terms for the D-block ions, the effect of crystal fields on these terms and the resulting D-D spectra of the ions.
When an atom becomes part of a molecule there are changes in the size and the shape of the charge-cloud associated with any one of the nuclei. If the atom forms a covalent bond to a neighbour, the size of...
The characteristics of ion exchange resins and an illustration of the physical and chemical laws which govern this phenomenon. Two examples of applications: the automatic analysis of amino acids on a...
Demonstrates the technique of mass spectrometry, showing how the instrument operates and how a mass spectrum is obtained. Also shows the relationship between precise molecular weight and the chemical...
Chemical reaction occurs as the outcome of certain types of molecular collision. The film deals mainly with the collision of atoms with diatomic molecules. It is composed of a number of specimen...
Looks at the way a molecular structure can build up through the repeated unit cell into a crystal lattice. Explains the main types of bonding which produce different types of crystal structure. Also...
The development and applications of the mass spectrometer and the difference between the direct-focusing and double-focusing mass spectrometer.*
After illustrating the extraordinary properties of water the film shows in animation how hydrogen and oxygen combine and examines the atomic structure of the water molecule, considering electrons first as...
