Highlights
  • 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
Read full description

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
