NMR Solvent Peaks vs Molecule Simulator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
NMR Solvent Peaks
This utility helps organic chemists quickly identify potential impurities by searching a database of NMR data. Users can input solvent, peak multiplicity, and location to find candidate impurities. It supports both proton and carbon data searches.
- Search for impurities by mode, solvent, multiplicity, and ppm
- View alphabetical list of all impurities
- Adjust user interface handedness
- Select color themes
- Supports proton and carbon NMR data

NMR Solvent Peaks is a conveniently-searchable version of the ungainly table of NMR data most organic chemists keep a copy of nearby. Instead of searching through the table for a peak near your unidentified peak, just enter your solvent and the peak's multiplicity and location and you'll have a short list of candidate impurities. NMR Solvent Peaks has support for searching both proton and carbon data, and references the widely-distributed 2010 Organometallics paper by Gregory Fulmer and coworkers and the 2016 OPRD paper by Gregory Whiteker and coworkers. Feature Highlights: - search for impurities based upon mode (proton/carbon), deuterated solvent, multiplicity, and ppm - select "show all" for ppm to see an alphabetical list of all impurities in the app's database - pick a color theme and adjust the user interface handedness
