title: Effects of ionizing radiation on dried spores of Osmunda regalis III. 35 GHz e.s.r. study.
abstract: The use of 35 GHz microwave frequency has greatly simplified the separation of overlapping signals in dried irradiated fern spores. While in general confirming the conclusions previously drawn from X-band spectra, the use of Q-band has clarified several assignments of radical groups and allowed the recognition of additional radical groups or sub-groups.
