iNMR — free NMR software for Mac and Windows

Free NMR Processing — Right Now

Need to process a spectrum immediately? iNMR runs in demo mode on Mac and Windows at no cost, with no registration and no expiry date. Every session gives you full access to all processing features — phase correction, baseline correction, integration, peak picking, and more.

When you are done, save your result as a PNG image using a standard system shortcut:

Press Cmd‑Shift‑4 (Mac) or use the Snipping Tool (Windows).
Select the portion of the screen you want to capture.

You can use iNMR in demo mode as many times as you like. It never expires. We hope you find it useful — and if you do, consider supporting its development with a license or a campus subscription.

“You have saved me countless hours stuck in a university computer lab and can now do lab reports from home. You guys are the best!” — Marcus Cogley, University of Alaska, Fairbanks
