1. The references listed in this bibliography include a majority of the important papers and books that are related to the development of microwave spectroscopy. General references relating to the basic concepts of rotational and, in a limited way, vibrational spectroscopy, are also included. Titles of dissertations, reports which have not been published in the open literature, and abstracts of papers presented at spectroscopy symposia generally are not given. Rather than a pure chronological listing, the references have been placed under specific topic headings whenever possible. A chronological order under these headings is maintained. Since a unique classification of each article is impossible, references which do not fall directly under one of the specific topics are listed in Section 12.
2. Several other bibliographies are available. Townes and Schawlow [20] compiled a complete listing up through 1954. In addition, Favero [35] has compiled a bibliography covering 1954 through 1962, and Starck [39] has completed one for 1945 through 1962. The latter is very useful because it is indexed by compound. This bibliography appears in a recent book [46a] by Sugden and Kenney. The bibliography listed here was previously published as U.S. Army Missile Command Report No. RD-TM-65–14, August 1965. It includes a majority of the references concerning microwave spectroscopy through 1965 and a number of references from early 1966.
