摘      要:The information derived from various C-13 nuclear magnetic resonance spectra has in most cases more fuzzy than crisp character. An approach to treat this information by means of the membership function is discussed. The combinatorial problems emerging from such a treatment are critically considered and a structure generation scheme consisting of multiple depth-first procedures is suggested. It permits to constrain the structure generation process through a non-redundant and flexible employment of the spectral information available.
