Elucidating ‘undecipherable’ chemical structures using computer‐assisted structure elucidation approaches [PDF]

open access: yesMagnetic Resonance in Chemistry, 2012
Structure elucidation using 2D NMR data and application of traditional methods of structure elucidation are known to fail for certain problems. In this work, it is shown that computer‐assisted structure elucidation methods are capable of solving such problems.
