Hi Marvin Developer,


while doing student courses with MarvinSketch we found the following bug:


The simulated 1H-NMR spectrum does not correspond to the structure symmetry, see attached screenshot.

Dear Csaba,


there is another example where the results do not correspond to the symmetry: pyrene.

Dear Hans-Ulrich,


I have been able to reproduce this bug, it is due to the same error.

Dear Csaba,


and it does not depend on the input: double bonds or aromatic rings, as it of course must be.

Dear Csaba,


good to read this. And I have a question: Is it (once more) possible to get a beta preview version?


I have some more problematic molecules and I would like to test it.

Dear Csaba,

Thank you.
