| Compare the scale btwn C-NMR & H-NMR |
|
Definition
C-NMR: 0 to 210 ppm
H-NMR: 0 to 12 ppm |

Term
13C NMR usually involve coupling? Why or why not?
What is one bond coupling? |
|
Definition
b/c 13C is rare so the chance of two 13 C atoms being adjacent is RARE
however ;
a '1 bond coupling' occurs btwn the carbon atom and the protons diretly attatched to them. |

Term
| does 13C need a small or large sample for analysis? |

Definition

|
Term
|
Definition
a feature of 13 C that allows spectrum to be recorded without the coupling of adjacent protons.
thus the spectra only concists of SINGLETS; each that are magentically equivalent |
|
|
Term
| again HNMR vs 13C-NMR who has multiplets , who doesnt? |
|
Definition
HNMR has multiplets
13C-NMR is rare and will already be adjacent to each other.
