Hi there,

how is possible that peak area calculated by ACD/NMR is lower than the same one calculated by MestReNova software. For example 3.70 vs. 3.97 creates 11% difference in conversion of polymerization.

Thank you, Frank

Also make sure that baseline correction is being done properly, or at least the same way, and the the integration limits are the same on the two programs. As a check, why not try it with TopSpin, SpinWorks, VNMRj or whatever else you may have available.

Hi Frank, Maybe you are using a different integration algorithm. Mnova has two algorithms for the integration: 'Peaks' and 'Sum'. If your peak is broad, the Sum algorithm is recommended. For further info, please get in touch with us
