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.
Novruz

Hi Ammrl,
Sorry to bother you all. I am hoping to draw on your extensive experience.
We are doing a large project where we are using NMR alongside MS to discover
unexpected discharges into the environment.
We have these very weird large signals in 1H NMR. They are quite strong even
in the unconcentrated effluent. I just cannot work out what they may be.
They are exclusive to effluents from the electroplating industry and appear
in some (but not all) discharges.
I have attached, a sheet of what we know. I am hoping someone somewhere may
have seen something like this before and can point us the right direction ?
Thanks so so much for your time, Cheers, Andre
