Hi Norvuz,
Thanks so so much.
Right now the leading theory is a phosphorus coupling such as
Indeed there is a good amount of phosphorous in the sample.
We have run fluorine and it is very low, but I think it is the phosphorous
used as a bleaching agent. We will run 31P NMR next week.
Thanks so so much, I really appreciate your time.
Cheers,
Andre

Hi Andre,
Can you get a 31P NMR or 19F NMR spectrum?
If there is a phosphorus peak and 1J(13P-1H) may be large.
Thanks.
