Norcamphor is an important norbornane scaffold that is often used in organic chemistry. Its near-symmetrical structure presents an exceptionally challenging second order 1 H NMR spectrum with heavy multiplet overlap (Figure ). The 5n and 6n protons are very strongly coupled (Dn !", = ca. 13 Hz, 3 JHH = 9.1 Hz), as are their geminal partners 5x and 6x to a lesser degree (Dn !", = ca. 34 Hz, 3 JHH = 12.0 Hz). Within the TSE-PSYCHE 29 1D pure shift spectrum, this results in reduced intensities relative to the other signals and in severe strong coupling artifacts close to the 5n and 6n signals (Figure ). Given the additional heavy multiplet overlap in the 1 H spectrum, it is near-impossible to individually invert any of these four protons. This makes the majority of 1 H-1 H couplings in this small molecule inaccessible with PSYCHEDELIC or (G-)SERF experiments. Marshall and Walter previously achieved full Jcoupling tabulation of norcamphor, but had to resort to syntheses of various selectively deuterated forms and spectral simulations. Whereas the 1 H spectrum of the all-12 C isotopomer is complicated, within the 13 C5 and 13 C6 isotopomers at least one 13 C spin isomer circumvents all strong coupling complications. The 13 C-decoupled HSQC in Figure reveals the 12 C-bound frequencies, while the CLIP-HSQC in Figure highlights the 5n[ 13 C a ] and 5x[ 13 C a ] satellites. From these, it can be seen that 5n[ 13 C a ] and 5x[ 13 C a ] are nicely resolved from the 6n[ 12 C] and 6x[ 12 C] multiplets, respectively. As all protons in the crowded region have geminal coupling partners, SATASERF has to be used. The experiment in Figure sets the WI-selective pulse to 5x[ 13 C a ] for observation, while the Ws-selective pulse is set to 6n[ 12 C], straightforwardly yielding the coupling between them. Similarly, the 13 C b satellites of both the 6x and 6n protons are wellresolved from their coupling partners, and Figure shows an example where the 5n-6x coupling is measured on the H6x[ 13 C b ] satellite. A final example in Figure shows the measurement of the geminal H6n-H6x coupling on the H6x[ 13 C b ] satellite. Of note is that the Ws-selective pulse should be set to H6n[ 13 C b ] rather than H6n[ 12 C] in this case, as the H6x[ 13 C b ] and H6n[ 13 C b ] signals come from the same isotopomer and 13 C spin isomer. Using various SATASERF experiments with judiciously chosen 13 C satellites, we could measure all couplings involving every proton in norcamphor without strong coupling complications. This includes verification of every conceivable long-range (i.e., more than three-bond) coupling in the molecule, which is a remarkable achievement given the complexity of the all-12 C isotopomer 1 H spectrum. An extensive revision of Marshall's coupling table is provided in the supporting information (Table ).
