๐งฒ Proton (ยนH) NMR Chemical Shifts โ Read the Signals! ๐ ยนH NMR helps you identify different hydrogen environments based on their chemical shift (ฮด in ppm). Here's your fast reference guide: ๐ Typical Chemical Shifts (ฮด in ppm): ๐จ 0.5โ2.0: Alkyl protons (CHโ, CHโ, CH) ๐ฟ 2.0โ3.0: Allylic, benzylic, or near heteroatoms โก 3.0โ4.5: Protons on carbons bonded to O/N/X ๐ฅ 4.5โ6.5: Vinylic protons (C=CโH) ๐ธ 6.5โ8.5: Aromatic protons ๐ 9.0โ10.0: Aldehyde ๐ง 10.0โ13.0: Carboxylic acid ๐ก Tip: More electronegative neighbors = higher ppm (downfield shift)! #ProtonNMR #H1NMR #NMRAnalysis #OrganicSpectroscopy #ChemistryTips #StudyGram #SpectroscopySunday #StructureSolver
