In reviewing Herman Mark s early years and rise to prominence as a physical scientist the author wishes to make special note of the use of an earlier profile of Prof. Mark by Morton M. Hunt (18), a special issue of Chemie Kunststoffe Aktuell (19), and two taped interview sessions with Prof. Mark (20, 21, 22). A special thanks is given to Ms. Jeanne Strauss, Phillips Petroleum Co., for her patience in clarifying a great deal of German for the author. 

Roald Hoffmann and Pierre Laszlo, "Representation in Chemistry," Angewandte Chemie, International Edition in English 30(1991) 116, on 5. These authors note that many textbooks incorrectly represent a molecule of camphor as the mirror image of the configuration given here, which is based on Hoffmann and Laszlo s diagrams (n., 4).

Note The process M H- X -> MX" + e , i.e., ionization of internally excited molecules upon interaction with other neutrals is known as chemi-ionization. Chemi-ionization is different from Cl in that there is no ion-molecule reaction involved [8,15] (cf. Penning ionization. Chap. 2.2.1). 

Rudolf Winderlich, 1876-1951. Advanced-studies adviser at the secondary school at Oldenburg in Oldenburg. Author of excellent textbooks containing valuable notes on the history of chemistry of the books Chemie und Kultur, Chemie fur Jedermann, and Das Ding and of many articles in educational journals. Contributor to Das Buch der grosscn Chemiker. See ref. (6Z).

Note The purpose of smooth or controlled blasting is to produce an excavation contour, while leaving behind an intact, fissure-free formation. This is done by the use of diminished-strength expl charges, using numerous boreholes, driven exactly in parallel Ref R. Meyer, Explosives , Verlag Chemie, NY (1977), 239 314... 

The a-carbon of each amino acid is attached to four different chemi cal groups and is, therefore, a chiral or optically active carbon atom. Glycine is the exception because its a-carbon has two hydro gen substituents and, therefore, is optically inactive. [Note Amino acids that have an asymmetric center at the a-carbon can exist in two forms, designated D and L, that are mirror images of each other (Figure 1.8). The two forms in each pair are termed stereoisomers, optical isomers, or enantiomers.] All amino acids found in proteins are of the L-configuration. However, D-amino acids are found in some antibiotics and in bacterial cell walls. (See p. 250 for a discus sion of D-amino acid metabolism.)... 

I1EII.STEIN, F. P. (1838-1906). A German chemist noted for his compilation Handbuch der Organischen Chemie, the first edition of which appeared in 1880. A multi volume compendium of the properties and reactions of organic compounds, it has been revised several times and remains a unique and fundamental contribution to chemical literature.
