Atoms and molecules can be made to communicate, and scientists have learned how to interpret their language.  Chemists’ knowledge of the interaction of radiation and matter is shown as the basis for analytical methods of sensitivity and specificity.  How such techniques are used in very different laboratory situations is examined.

Running Time:  28:38

     Journey through the exciting world of chemistry with Nobel laureate Roald Hoffman as your guide.  The foundations of chemical structures and their behavior are explored through computer animation, demonstrations, and on-site footage at working industrial and research labs.  Distinguished scientists discuss yesterday’s breakthroughs and today’s challenged.
