Here is the replacement image Bryan Derksen had been working on with Wikipedia timelines, copied from the image page in case there was not a publicly accessible backup:

To the above "bar graph" on ¹³C chemical shifts of various organic groups, I have added the 0.0 ppm standard TMS and resized it and repositioned it within the article, as well as resizing/repositioning the vanillin spectrum. H Padleckas (talk) 21:37, 4 March 2009 (UTC)[reply]

The vanillin C-13 NMR spectrum pic has been deleted and taken out of here due to its questionable copyright status. Unfortunately at this time, there is no suitable replacement example C-13 NMR spectrum image available at this time. A C-13 NMR pic of quinoline in WikiCommons is about to be deleted because of lack of source information, so that was not put in this article. H Padleckas (talk) 08:00, 25 January 2012 (UTC)[reply]

Here is the C-13 NMR picture of quinoline from File:Chinolin 13C.JPG under threat of deletion:

In the image of shifts, shouldn't R-CH2-O (and RCH2O) be R-CH2-OH or R-CH2-OR? Also, for RCH2X: X=N should be X=NH2 or NR2. Narky Blert (talk) 12:20, 18 February 2017 (UTC)[reply]

Assessment comment

The comment(s) below were originally left at Talk:Carbon-13 nuclear magnetic resonance/Comments, and are posted here for posterity. Following several discussions in past years, these subpages are now deprecated. The comments may be irrelevant or outdated; if so, please feel free to remove this section.

There is a mistake in the DEPT section. An angle of 90 degrees shows the CH2 groups, not the CH groups as the text says.

External links modified (January 2018)

Hello fellow Wikipedians,

I have just modified one external link on Carbon-13 nuclear magnetic resonance. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Added archive https://web.archive.org/web/20150302024127/http://www.chem.wisc.edu/areas/reich/handouts/nmr-c13/cdata.htm to http://www.chem.wisc.edu/areas/reich/handouts/nmr-c13/cdata.htm

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.
