Spectroscopic Tricks was introduced in 1959 as a special section in the journal Applied Spectroscopy. Its purpose was to provide a means for communicating information on new devices, modifica tions of existing apparatuses, and other items of this nature of interest to the working spectroscopist. That it has proved valuable is indicated by the continuing publication of this section now under the title of Spectroscopic Techniques. However, the use fulness of these contributions, scattered through the many issues of the journal, diminishes as time passes since the reader must consult the annual indices of many volumes of the journal to find the contri bution that may hold the solution to his problem. The collection of the contributions into a single volume for the years 1959 through 1965 made it easier for the reader to make this search. The success of the first volume has prompted the continuation of these collec tions. The contributions in this second volume are selected from the the years 1966 through 1969. They are arranged in the same manner as in the previous volume according to the area of spectroscopy. Those concerned with the same devices are placed together so that the reader can compare them readily. To maintain the advantages inherent in a single collection of articles, the subject index for this volume includes all the entries and page references from the original volume. Both author and journal indices are are also provided, the latter citing the original Applied Spectroscopy edition.
