WebApr 21, 2024 · Today, the focus will be on specific regions of chemical shift characteristic for the most common functional groups in organic chemistry. Below are the main regions in the 1 H NMR spectrum and the ppm values for protons in specific functional groups: The energy axis is called a δ (delta) axis and the units are given in part per million (ppm). Weba) Use ChemDraw or ChemSketch to copy-and-paste a compound structure into your 1H 1D spectrum; CNTL-C and CNTL-V work fine for this. Note: I (cgf) have been unable to get renumbering in ChemDraw to replicate in MNova, whereas the renumbering in ChemSketch is reproduced. In fact, pasting the ChemDraw
