After more than a century since its birth, Quantum Theory still eludes our under1 standing. If asked to describe it, we have to resort to abstract and ad hoc principles about 2 complex Hilbert spaces. How is it possible that a fundamental physical theory cannot be de3 scribed using the ordinary language of Physics? Here we offer a contribution to the problem, 4 providing a short non-technical p...

ABSTRACT Advances in Nuclear Magnetic Resonance (NMR) spectroscopy is a cornerstone structure elucidation of polycyclic 'cage' scaffolds. Due to the compactness these compounds, much overlap, as well unique through-space and bond NMR interactions are frequently observed. This review serves guide for future derivatives by providing some typical relevant aspects characteristic trends, substituent...
