60 MHz 1H NMR Reaction Monitoring
Visualization and Quantitation with MestReNova Software
MestreNova NMR post-processing software from MestreLab Research SRL has been
a big improvement on our ability to rapidly process real time reaction data
obtained on our AspectItalia 60 MHz NMR system.
Reaction System: Acetylation of t-butyl alcohol with acetic anhydride in the presence of acid.

The MNova data analysis tools allow the user to integrate NMR reaction peaks
and automatically plots and fits them to exponential time constants allowing
detailed kinetics to be extracted rapidly and easily from the data. What
used to take hours of lining up ascii spectra in excel or other software now
literally takes seconds. The integration is segmented in such a manner that
integrals can be made to track with shifting resonances, for example labile
protons effected by pH.
