Follow-up to the last question.
The chemical formulation in this patent (colorant for hair) contains the term "breit" e.g.: 1H-NMR (300 MHz, DMSO): 7.9-7.0 (s, breit, 4H, OH and NH3+); 6.56 (d, J=1.8,1H, H(2)); 6.50 (d, J=8.1, 1H, H(5)); 6.41 (dd, J=1.8, J=8.1, 1H, H(6)); 3.35 (s, 2H, CH2-C=O); 3.41 (t, 2H, J=6.6, N-CH2); 3.26 (t, 2H, J=6.6, N-CH2); 1.89-1.69 (m, 4H).
Can anyone tell me what this could possibly mean?
Sorry I cannot give more context than that. It appears like this every time in the document.
Thanks,

This explains the form of the band (all the nice peaks and bumps you can see on the print-out) you get in a chromatography of the product and is often just given as br (same in English and German).

Sorry, of course it\'s less a form than a shape.

: The text is talking about an NMR analysis. I agree, you say broad

My fault: of course it's an NMR analysis.

No idea why, but s-broad can be found in English texts dealing with similar chemicals, and the authors can't all be misled Germans...
Discussion
the "m"s that you see are "multiplets": peak divided many time. The "J's are "spin coupling constants": they mediate coupling of nuclear spins ---> splitting. "d" stands for doublet, "s" for singlet, "q" for quartet.
constantly moving ... the picture will be fuzzy. well, in NMR broad is fuzzy,,, loss of information.
Sharp peaks are highly prized!
So the neighboring C does not have hydrogens. Whay broad? many reasons (hydrogen bonding, etc.).
OH H-signals are broad becuase the hydrogen jumps...
