Scientific paper

In a program designed to increase our knowledge of fundamental properties of main-sequence stars with masses 1.1 Msun or less, for which little information is currently available, high-resolution spectra have been obtained of 76 eclipsing binaries of types reported to be F5 or later. Included in the program are binaries for which relatively little spectroscopic material is available as well as binaries for which considerable improvement of existing orbits is desired. The number of spectra obtained per binary by 1995 November varies from 1 to 58. Of the systems, 16 are considered to be promising candidates for mass determination, with an additional 17 considered potentially useful. Comments are included on each of the systems.
