I'm using ChemBioDraw in order to analyze structures for a lab report. When I draw p-bromophenol or p-nitrophenol, the 1H NMR prediction seems to have a bug - sometimes the substituents aren't recognized, or H is placed in the wrong place. For some reason either a C will not be recognized as having an H, or it will have too many. Sometimes it works properly. Any help to fix this would be appreciated.

Hello,

I've got the same bug.

If I try to predict the NMR spectrum of a benzene with two subsitutes I find two carbons having two H, and a strange spectrum (clearly it's wrong).

Anyway chemical properties say that benzene template is right.

It should be a bug of the spectrum file. any fixing way?
