iNMR 7: faster results, less friction

Extracting and reporting chemical shifts and J-coupling constants has never been faster. The built-in J Manager simplifies the entire workflow — from raw data to publication-ready tables in ACS, RSC, or custom formats — saving hours of tedious manual work per manuscript. Now, version 7 takes it further. The new Prediction command connects directly to nmrdb.org, showing your assigned spectrum instantly—no dialogs, no delays. With the unified Comparison tool, you can match signals and validate results for both ¹H and ¹³C in seconds. Not revolutionary, only evolutionary, but it will save you five minutes.

In the past, iNMR relied on pre-processed frequency domain files. Today, that limitation is gone. iNMR 7 now handles Non-Uniform Sampling (NUS) by processing the raw time-domain data directly using a sophisticated Iterative Soft Thresholding algorithm.

Thanks to full parallelization, reconstruction is incredibly fast—often completed in a fraction of a second. For those seeking the highest possible accuracy, you can optionally let the engine run deeper for a few seconds more.

The interface is designed for simplicity: there is only one parameter to adjust. And don't worry—the default setting is already optimized to give you excellent results right out of the box.

The core simulation engines—spin system modeling and chemical exchange—have been re-engineered for parallel computing. iNMR 7 can now simulate systems of up to 13 spins with unprecedented efficiency.

For systems with 11 spins or fewer, the calculation is instantaneous. This speed enables the seamless, real-time feedback that long-time users rely on: as you tweak any parameter, the simulated spectrum updates before your eyes.

Adjusting chemical shifts is intuitive. Simply grab the red labels with your cursor and drag them; the simulation follows your movement, allowing you to match experimental data with pinpoint accuracy and zero lag.

iNMR 7 intelligently detects if Open Babel is installed on your Mac, seamlessly delegating complex molecular tasks to this powerful engine. For instance, it can automatically convert ChemDraw formulas into MOL format, extracting vital data like elemental formulas, molecular weight, and SMILES strings.

The practical applications are game-changing: you can view the molecular formula of a spectrum directly from the Finder without even opening the app. Searching your entire archive for spectra of a specific compound or generating instant predictions becomes an effortless, organized process.

Think of iNMR as your digital assistant, keeping your metadata perfectly structured and accessible exactly when you need it.

Note: This advanced integration is exclusive to the macOS version.

The comprehensive user manual is now built directly into the application, leveraging the native macOS Help system. This integration allows you to search for keywords across the entire manual and within the app's menus simultaneously, ensuring you find the right command or explanation instantly.

To make learning even more fluid, every dialog box is context-linked to its corresponding manual page. Help is never more than a click away, right when you need it most.

Note: The Windows version connects seamlessly to the web-based version of the same manual.

In recent years, macOS changes caused a frustrating side effect: whenever a dialog appeared, the main window would dim, obscuring the very spectrum you were trying to process. iNMR 7 fixes this, restoring the full visual clarity the software was designed for.

iNMR has always been about interaction. While other programs force you to type a number and click "OK" to see a change, iNMR lets you move a slider and watch the results in real time. By eliminating the "dimming" effect and making dialogs fully movable, we've removed the barriers between you and your data.

No more hidden signals. No more visual fatigue. You are back in total control of your workspace, with every adjustment visible the moment you make it.

Note: Windows users have always enjoyed this behavior, which is now fully optimized for Mac as well.

The best installation process is the one you don't even notice. We have worked hard to make the transition to version 7 as seamless and natural as possible.

iNMR is now a fully notarized application from a Verified Apple Developer. This means you can say goodbye to those alarming security warnings and system blocks. From the moment you download it to the first time you launch it, the experience is smooth, safe, and professional.

The Original Parameters command opens a dedicated window displaying all acquisition data exactly as it was recorded on the spectrometer. You can review, print, or copy these values with a single click.

This feature supports Bruker, Varian, and Jeol Delta files. While Bruker and Varian parameters are stored in text files, iNMR saves you the trouble of hunting through subfolders; it knows exactly where to look and which files to retrieve for you.

For Jeol users, iNMR 7 provides a massive advantage. These parameters are stored in a complex binary format that used to require "hacker-level" skills to decode. Now, iNMR does the heavy lifting for you, presenting everything in a clear, readable format.

The new icon marks a return to our roots, reimagining the classic SwaN-MR symbol for the modern digital landscape. This icon carries 33 years of history; it has never truly left us, living on as the familiar favicon in your browser tabs and bookmarks for decades.

Returning to these origins means bringing over thirty years of experience into play. It represents our 100% belief in what we do and our restless desire to reach perfection. We never settle for "good enough"—we strive for the best.

iNMR 7 is the foundation for a new beginning. Every detail tells us that the best is yet to come. Our story is moving forward with bold steps, and many more features are already on the horizon—all of which, as always, will be provided as free updates.

Above all, the spirit we’ve built over these 33 years remains: the passion and the ability to listen to you, our users, and turn your feedback into the tools of tomorrow.

Start your free trial today. You can test every single feature (excluding printing and saving) right away—no unlock code required. If you need a temporary license key for a full evaluation, simply request one via email.

The only thing we don’t provide is the computer, but that won’t stop you. iNMR runs smoothly on any machine from the last 15 years, including legacy systems running Windows Vista or OS X El Capitan.

Compatibility doesn't mean compromise: iNMR 7 is, of course, a native Apple Silicon application, fully optimized for the latest M1, M2, and M3 processors.
