Rohan Paul@rohanpaul_ai · XAnthropic最新化学报告显示，通用大模型Claude Opus 4.7（无化学微调）在NMR核磁共振谱分析上匹配甚至超越专用软件MestReNova，氢预测误差最小，碳预测近乎一致。更关键的是，它能从NMR光谱反向推导分子结构——这一任务以往只能由人类化学家完成。这意味着AI现在可以处理化学中的关键瓶颈：在分子结构、谱图与最终确认之间自动翻译。
Anthropic's new chemistry report has a genuinely wild result.
Claude Opus 4.7 is now competitive with dedicated NMR software， and the bigger story is that it can work the problem backwards， i.e. infer the molecule from the spectrum."
NMR software is the chemist's expert tool for turning molecular structures into predicted lab spectra.
So Opus 4.7 is no longer just "helping chemists read data" - it can work backward from NMR data and propose the molecule's structure， a task the report says existing mainstream tools generally leave to human chemists.
Note， that Opus 4.7， a general-purpose model with no chemistry-specific fine-tuning.
Claude Opus 4.7 made the smallest hydrogen prediction errors and nearly matched MestReNova on carbon， meaning it can predict NMR signals about as well as specialist chemistry tools.
So AI now handle one of chemistry's hidden bottlenecks： translating between a molecule， its spectral shadow， and the structure a chemist actually needs to trust.
