title: Absorption of DNA in the region of vacuum-uv (3-25 eV).
abstract: By means of a device that might be considered a modern version of "Ulbricht's sphere" the absorption spectrum and the photoelectric emission of calf thymus DNA was measured in the region of 3 to 25 eV (400 to 50 nm). A tentative explanation of the general shape of the absorption spectrum and of its 6 maxima is given. The results permit a much better insight into some biologic effects of vacuum-uv to be gained than hitherto possible.
