Polycyclic hydrocarbons may be named in a variety of ways. These include several kinds of systematic names, recommended by the International Union of Pure and Applied Chemistiy (lUPAC) [93-ano-l], indexing names used by Chemical Abstracts, and various trivial and other names found in the chemical literature. 

Mixtures of either chemically identical or dissimilar macromolecules are polymer mixtures and polymer blends, respectively. Polymer blends can be mo-lecularly homogeneous or, more commonly, heterogeneous. Distinct phases are present in the latter polymer blends. The often employed term polymer alloys is not recommended by the International Union of Pure and Applied Chemistiy, lUPAC. 

There is currently no generally used spectral format in NMR. However, the International Union of Pure and Applied Chemistiy (lUPAC) has a working party that expects to produce a JCAMP-based multidimensional NMR data standard by March 2000. 

When a scientist discovered a new element in the early days of chemistiy, he or she had the honor of naming it. Now researchers must submit their choices for a name to an international committee called the International Union of Pure and Applied Chemistry before they can be placed on the periodic table. In 1997, the lUPAC decided on names for the elements from 104 through 111. These eight elements are now called rutherfordium (Rf), dubnium (Db), sea-borgium (Sg), bohrium (Bh), hassium...
