NMR Spectroscopy Tutor vs K

Learn to turn NMR signals into molecular structures—not just memorize peak tables. NMR Spectroscopy Tutor puts spectrum interpretation into your hands. Explore ¹H NMR, ¹³C NMR, and DEPT data in an interactive spectrum viewer. Zoom and pan, select peaks, collect chemical evidence, and assemble a molecular structure one piece at a time. Three ways to build confidence: LEARN Follow guided lessons and worked examples. Build a foundation in chemical shifts, integration, splitting, coupling, equivalence, molecular formulas, degree of unsaturation (DBE), and carbon types. PRACTICE Work through structure-solving problems with helpful coaching. Examine each signal, connect the clues, and learn why a structural feature fits the evidence. MASTER Take on spectrum challenges more independently. Use what you know to go from NMR observations to a complete structure. Explore key skills: Interpret ¹H chemical shifts, integrations, multiplicities, and coupling constants Use ¹³C and DEPT spectra to distinguish carbon environments Combine a molecular formula and DBE with spectral evidence Recognize alcohols, ethers, esters, aldehydes, ketones, and aromatic groups Build molecules from evidence instead of guessing from a list Built for organic chemistry students, spectroscopy learners, and instructors looking for a visual teaching companion. From your first peak to your final structure, learn the reasoning behind NMR.

**The Molecular Model App We Always Wanted** Born from the developer’s own learning experience, K-Mol is a molecular modeling app designed for high school and university students. ## Features ### 2D Mode ・Draw structural formulas with intuitive controls ・Supports up bonds and down bonds, making it possible to represent stereochemical structures ・Includes templates for five-membered and six-membered sugar rings, saving you from the tedious process of drawing them from scratch ### 3D Mode ・A 3D mode that feels like using a real molecular model kit ・A practical alternative to physical molecular model kits, which can be surprisingly expensive ・Recreates bond lengths and bond angles, making it useful for learning from the high school level through university-level chemistry ・viewing molecular models in AR ## Shared Features ・Screenshot: Capture the structural formulas and 3D models you create. Perfect for reports and study materials. ・Save: Save your structural formulas and 3D models inside the app and reopen them anytime. ・Templates: Frequently used structural formulas are available as templates, so you do not have to draw everything manually. ## Important Notes K-Mol is an educational app designed to help students learn about molecular structures, bonds, stereochemistry, and basic chemical visualization. It is not a substitute for textbooks, classroom instruction, laboratory safety guidance, or professional chemical analysis. The molecular structures, bond lengths, bond angles, aromatic representations, templates, and 2D/3D views shown in the app are simplified models for educational purposes. They do not fully represent actual chemical behavior, quantum effects, force-field optimization, experimentally measured structures, or other advanced chemical properties. Do not use this app for laboratory safety, medical, pharmaceutical, environmental, industrial, regulatory, research-level modeling, synthesis planning, handling of hazardous substances, or any other professional or safety-critical purpose. This app does not provide professional advice. The information displayed is intended for general educational purposes only.
