MAJOR SYMBOLS<br />

Listed below are symbols used in several chapters or in large portions of a chapter. Symbols<br />

similar to some of these may have different local meanings. In most cases, the usage<br />

follows the recommendations of the IUPAC Commission on Electrochemistry [R. Parsons<br />

et al., Pure Appl. Chem., 37, 503 (1974).]; however there are exceptions.<br />

A bar over a concentration or a current [ej*., C o<br />

(x, s)] indicates the Laplace transform<br />

of the variable. The exception is when / indicates an average current in polarography.<br />
