Anthropic says it is working with synthetic, computational, and analytical chemists to make Claude better at chemistry, and this first post from that effort focuses on one of the most common tools chemists use, NMR spectra. Anthropic tested Claude on NMR chemistry tasks, where chemists use spectral data like a molecular fingerprint to confirm what they made. They compared Claude against tools like ChemDraw and MestReNova on 20 molecules, and Opus 4.7 did surprisingly well. It was best overall fo...
