Which is the unstructured region of a 13 C NMR?
In general, when you state analyzing a 13 C NMR, split the spectrum in two parts by drawing a line at 100 ppm; below this value you have the saturated functional groups, and beyond that is the unstructured region. So, saturated carbon atoms connected to electronegative heteroatoms give signal from 30-90 ppm.
What are the regions of chemical shift in NMR?
Today, the focus will be on specific regions of chemical shift characteristic for the most common functional groups in organic chemistry. Below are the main regions in the 1 H NMR spectrum and the ppm values for protons in specific functional groups:
Which is the reference point for a carbon NMR?
Just like the 1 H NMR, the reference point is the signal from TMS which again is set to 0 ppm. So, ignore this peak when analyzing a carbon NMR. Most organic functional groups give signal from 0-220 ppm. Here as well, the carbons connected to electronegative elements resonate downfield (higher energy).
What is the NMR spectrum for 13C hydrochloride?
The 13 C NMR assignments for the observed resonance bands associated with the various carbons are listed in Table 7.
