The present collection of articles follows the arrangement used in previous volumes. Solutions are discussed first, surfaces and double- layers second, electrode kinetics third, and then the applied subjects. The introduction of spectroscopic methods to electrochemistry is well exemplified by NMR studies of ionic solutions, as represented here in the detailed article by E. von Goldammer. Correspondingly, the spectroscopic approach can be applied to surfaces, and B. G. Baker has written an introduction to this topic for electrochemists from the point of view of gas phase measurements. One of...
