Pure NMR vs Idetick

Pure NMIdentify NMR impurities instantly with Pure NMR. Pure NMR is the essential reference tool for chemists working with NMR spectroscopy. Quickly identify unknown peaks in your ¹H and ¹³C spectra by searching a comprehensive database of common laboratory impurities and residual solvents. FAST & ACCURATE SEARCHES Enter a chemical shift value and instantly find all matching impurities within your specified tolerance range. Search across multiple deuterated solvents including CDCl₃, DMSO-d₆, CD₃CN, D₂O, and more. COMPREHENSIVE DATABASE Access chemical shift data for over 60 common impurities including: Residual solvents (water, acetone, ethyl acetate, etc.) Common reagents (triethylamine, acetic acid, TMS, etc.) Laboratory contaminants (silicone grease, pump oil, etc.) Stabilizers and additives (BHT, BHA, etc.) All data is based on peer-reviewed literature (Fulmer et al., Organometallics 2010; Gottlieb et al., J. Org. Chem. 1997). KEY FEATURES - Search by chemical shift (1-H or 13-C) - Adjustable tolerance range (0.0 to +/-1.0 ppm) - Support for 14 deuterated solvents - View complete assignment information (multiplicity, coupling constants) - Add your own custom impurities to the database - Browse all impurities by solvent - Dark mode support - Customizable interface colors - No internet connection required - fully offline PERFECT FOR Organic chemists characterizing compounds Graduate students learning NMR spectroscopy Research scientists in academia and industry Anyone who needs quick impurity identification SCIENTIFICALLY VALIDATED All chemical shift values are sourced from authoritative scientific publications, ensuring accuracy and reliability for your research. EASY TO USE Select your nucleus (1-H or 13-C) Choose your deuterated solvent Enter the unknown chemical shift Get instant results with full spectroscopic details Stop flipping through reference books or searching online databases. Pure NMR puts all the essential impurity data right at your fingertips. PRIVACY FOCUSED Pure NMR works completely offline. No data collection, no tracking, no internet required. Your searches stay on your device.You can also custom save the Default conditions so that every time the App starts up, you are ready to go without having to select them again.

Stop reading the same page five times and hoping it sticks. idetick turns photos, videos, PDFs, and notes into AI-generated visual flashcards and mind maps — in seconds. Snap it, paste it, or speak it. Your deck builds itself. SIX WAYS TO CREATE FLASHCARDS Snap a photo of a textbook. Paste a YouTube link. Upload a PDF. Drop in a URL. Record a lecture. Or just type a topic. idetick reads it, breaks it down, and builds custom visual flashcards — flowcharts, timelines, comparisons, diagrams — with the AI selecting the right format for the content. KNOWLEDGE MAPS Once you've reviewed a deck, idetick generates a visual mind map connecting every concept. See how ideas relate, reveal the gaps, then test yourself by rebuilding the map from memory. SIX QUIZ MODES Adaptive Quiz — adjusts difficulty in real time, rated per card Visual Quiz — identify the concept from the infographic alone Match Game — drag and drop to pair answers Mind Map Rebuild — reconstruct the knowledge map from memory Cram Mode — fast-paced, all cards, no spacing algorithm Smart Mix — cross-deck quiz pulling from everything you're studying SPACED REPETITION BUILT IN Every card is scheduled automatically. Hard cards come back sooner. Mastered cards space out. You study what you need — nothing more, nothing less. PROGRESS YOU CAN SEE Daily goal rings. Weekly study heatmaps. Confidence vs accuracy calibration. Weak areas surfaced automatically so you know exactly where to focus before an exam. THE SCIENCE BEHIND IT Built on the science of how memory actually works: pair images with text and you remember more. Space your reviews and you forget less. Test yourself and it sticks for good. The AI picks the right visual — flowchart, timeline, comparison, diagram — because each concept needs a different format. This isn't passive reading dressed up with pictures. It's studying engineered for retention. WHO IS IDETICK FOR? Students revising for GCSEs, A-Levels, and uni exams. Visual learners who need to see it to remember it. Homeschooling families who want interactive materials. Teachers building accessible resources. Anyone who's ever stared at a textbook and thought "none of this is going in." PRICING Free — Text flashcards from PDFs, YouTube, URLs, or typed topics. Core quiz modes included. Pro ($9.99/month) — AI visual infographics, camera & audio input, knowledge maps, adaptive quiz, advanced analytics. 50 visual credits/month. 7-day free trial. Ultimate ($19.99/month) — Everything in Pro. 200 visual credits/month. Bulk regeneration. 7-day free trial.
