Chemical Titles, and readily available journals ending November 30, 1973. This period has seen a continued growth in the use of polarography and related electrochemical techniques to follow chemical reactions and to supplement other physical and spectral measurements for purposes of characterization. Interest in applications toward biochemical and pharmaceutical problems has also increased. There also appears to be renewed interest in utilizing polarographic and related electrochemical data to predict and follow organoelectrochemical synthesis.In this review the symbols cv, dc, ac, and op are used to identify cyclic voltammetry, direct current polarography, alternating current polarography, and oscillographic polarography, respectively. Also, no attempt was made to list all organic polarographic references.
