We have learned about 1H-NMR spectroscopy in the previous parts, now we will learn about another NMR spectroscopy that is 13C-NMR spectroscopy.

 

              1. Students understand why 13C-NMR spectroscopy is developed after 1H-NMR spectroscopy.

              2. Students understand why 13C-NMR chemical shifts have similar properties to 1H-NMR chemical shifts.

              3. Students understand why proton-coupled spectra are more complicated and why we have to use decoupling techniques.

              4. Students understand principles of decoupling and DEPT techniques.

              5. Students can interpret decoupled and DEPT spectra.

 

There are 6 subtitles of 13C-NMR Spectrosopy;

              6.1 Introduction

              6.2 C-13 Chemical Shifts

              6.3 Proton-Coupled Spectra

              6.4 Spin-Decoupling in C-13 NMR Spectroscopy

              6.5 DEPT Techniques

              6.6 C-13 NMR Problem Set

 

              1. Why does 13C-NMR spectroscopy is developed after 1H-NMR spectroscopy?

              2. What does decoupling mean?

              3. Why do we have to use decoupling spectra instead of proton-coupled spectra?

              4. What is DEPT techniques and do they important for structural elucidation?
