    Am I the only one who can't do this for the life of me no matter how many videos I watch ?

      Break the spectrum down one peak at a time.
      Splitting pattern tells you how many Hs are adjacent to the ones causing the signal
      Area tells you how many Hs are causing the signal
      Shift tells you the environment the Hs are in
      Then if you can, draw out that part of the molecule.
      Repeat for the other peaks
      If it’s any consolation, most students hate NMR
      It does get easier with practice. That’s why I’ve made so many walkthroughs!!

    Sir do I need to memorize the chemical shift values for H and C-13 NMR according to CIE syllabus 2023?

    • @MaChemGuy

      Can’t believe you have to do that. They will be given on a data sheet surely
