12+ Cdcl3 Peak Background. Recall that quaternary carbons are often shorter than protonated ones (this is due to. But in 13c nmr of dmso its peak appeared as septate.
(2) does the spectrum have 9 signals in it? 182k likes · 1,046 talking about this. However, whenever cdcl3 is used as an nmr solvent, a small singlet is always observed at 7.26 delta.
What is this peak due to and why the heck is it there?
2.82 (t, 2h, j =7), 2.01 (s, 1h, peak disappears in d 2 o) compound b: In chloroform solvent (cdcl3), this corresponds to chcl3, so a singlet signal is observed at 7.26 ppm. Clearly, there are more than 9 signals height of peaks. If solvent peaks are not properly recognized (3).
