Precision space‐filling atomic models

Abstract Shortly, lightweight, inexpensive, precision, space‐filling atomic models particularly suitable for constructing macromolecules of biological interest will reach the scientific community. The availability of the models, the Corey‐Pauling‐Koltun, or C‐P‐K Models, will conclude a five‐year program which has involved the cooperative efforts of Federal agencies, scientific societies, and selected scientists. This paper describes the development of the program, details the contributions of the various groups and persons who have been involved, and discusses the technical characteristics of the models.
