Wiley expands spectral libraries with major updates to IR, Raman, and LC-MS collections

Wiley, a global leader in authoritative content and research intelligence, today announced the release of additional data to its IR, Raman, LC-MS, and SmartSpectra libraries, significantly broadening compound coverage. The expansion brings Wiley's spectral database offerings to over 9.5 million high-quality spectra, delivering researchers enhanced capabilities for faster, more confident compound identification. 

"These updates deliver what researchers need most: broader coverage and greater confidence in their identifications," said Graeme Whitley, senior director, Wiley Science Solutions. "By expanding our empirical collections, including updates to our renowned Sadtler IR and Raman libraries, alongside our SmartSpectra databases, we're providing quality data researchers can rely on to make critical decisions across their analytical workflows." 

Subscribers automatically gain access to new data, ensuring labs always have the most current, reliable reference libraries to improve analysis, reduce errors, and increase productivity.
