Abstract
The electron nuclear double resonance spectra of the protons in fluorenylidene molecules in the ground triplet state in a single crystal of diazofluorene have been studied. The directions of the principal axes of the proton hyperfine interaction tensor have been found, and the values of the components of this tensor in its principal axis system and in the principal axis system of the fine structure interaction tensor, are given. Best values of seven distinguishable spin densities have been determined on the basis of several models.Keywords
