| T111 | 39-45 | Sentence | denotes | 2.1.2. |
| T112 | 46-56 | Sentence | denotes | 1D 13C-NMR |
| T113 | 57-186 | Sentence | denotes | Compared with 1H, 13C has a much higher chemical shift dispersion (~200 ppm), however the natural abundance of 13C is low (1.1%). |
| T114 | 187-351 | Sentence | denotes | Additionally, the gyromagnetic ratio is ~4 times weaker than 1H and therefore 13C spectra are far more difficult to obtain especially for less concentrated samples. |
