Predicting chemical shifts with graph neural networks

Abstract: Inferring molecular structure from Nuclear Magnetic Resonance (NMR) measurements requires an accurate forward model that can predict chemical shifts from 3D structure. Current forward models are limited to specific molecules...

“…The simulation duration was 1.3 µs with frames saved for this analysis every 500 ps. To compute the chemical shift, g k , we use a graph neural network that can compute chemical shift from atomic positions [73]. We only biased backbone HN atoms, due to their higher accuracy [73].…”

“…Recently a GNN architecture was described that can capture the effect of noncovalent interactions and secondary structure effects on chemical shis of C, N and H nuclei in biomacromolecules and organic molecules. 33 Empirical approaches to NMR chemical shi prediction use interatomic connectivity to dene the local neighborhood around a given atom, while the effects of stereochemistry and molecular conformation are most oen ignored. However, geometric factors play a fundamental role in inuencing chemical shi.…”
