Identifying the carbon from C13 NMR spectrum
Click For Summary
The discussion centers on the molecule p-phenetidine, highlighting the chemical shifts observed in its NMR spectrum. Aromatic carbon atoms are noted to appear very upfield, while carbon atoms bonded to oxygen (C-O) and nitrogen (C-N) are positioned more downfield, though still slightly upfield compared to carbon-carbon (C-C) bonds. The conversation concludes with a participant expressing gratitude for the clarification and confirming their understanding of the topic.

In general: aromatic Cs are very upfield, C-O and C-N carbons are more downfield, but slightly more upfield than C-C carbons.

Oh ok thank you I have figured it out nowMayhem said:
If nothing else it's a thing to stare at and wonder about for a bit.
