Introduction to NMR Spectroscopy

Introduction to NMR Spectroscopy. Part II ( 13 C-NMR). 13 C-NMR Spectroscopy - Introduction. The 13 C-atom possesses like protons a nuclear spin of I =½ Unfortunately , the signals are much weaker because of the lower natural abundance of the 13 C-isotope (~ 1 %)

Introduction to NMR Spectroscopy

Introduction to NMR Spectroscopy. Part III (DEPT and 2D-Methods). DEPT-Introduction. Recall that most 13 C-NMR are acquired as proton decoupled spectra because of the 13 C nucleus is significantly less abundant than the 1 H nucleus

Introduction to C-13 NMR

Introduction to C-13 NMR. The 13 C nucleus is present in only 1.08% natural abundance. Therefore, acquisition of a spectrum usually takes much longer than in 1 H NMR. The magnetogyric ratio of the 13 C nucleus is about 1/4 that of the 1 H nucleus.
