Key Points

1Opus 4.7 achieves top accuracy on ¹H NMR (±0.079 ppm)
2Inverse analysis succeeds 100% on simple structures, high rate on complex ones
3Proposes structures from 1D NMR alone without specialist software

Anthropic compared Claude Opus 4.7's NMR analysis performance with ChemDraw and MestReNova. It matches or exceeds specialist tools in forward prediction and enables inverse structure elucidation. This can reduce daily workload for chemistry researchers.

Key points

Anthropic validated Claude's NMR forward prediction and structure elucidation on 20 compounds. Opus 4.7 matches or exceeds ChemDraw/MestReNova accuracy, and inverse analysis works without specialist tools.

Impact

AI can now assist routine chemistry analysis, improving research efficiency. Note the evaluation scale is small as a limitation.
