In summary, the successful counting of 31 P nuclei clustering in vitrified solutions provides a novel structural analysis approach to characterize nonclassical growth pathways that include pre-nucleation clusters as intermediate species. In the future, these MQ-SC experiments can be optimized to better resolve the higher order coherences using finer phase increments to better resolve their higher precession frequencies compared to that of lower order coherences. It should be possible to see a more distinct transition from higher coherence orders that are present vs those below noise levels to figure out the upper bound quantum number by sampling the precession frequencies with increasingly finer phase increments.
