- This is a spectrum of di-n-butylamine. I'm really not good with spin systems and would like your help. I thought secondary spin systems would only occur when the chemical shift is similar to the coupling constant. But this doesn't seem to be the case for the triplets.
J is 7.2 and 7.1 for the triplets (7.2 for the pentet, 7.1 for the sextet), chemical shift 0.93 and 2.62
Also is it a AMSX or AMX spinsystem?
