NMR初心者必見：CDCl₃でよく見かける残留溶媒・不純物ピーク

How to Spot Residual Solvent and Impurity Peaks in 1H NMR (CDCl₃) — A Beginner’s Guide

Abstract:
Nuclear Magnetic Resonance (NMR) spectra often contain extra “mystery” peaks that don’t belong to your target molecule. This Substack-style article introduces beginner organic chemistry students to common residual solvent and impurity signals in 1H NMR, focusing on CDCl₃ solvent. We explain what residual solvent peaks are and why they appear, a…
