![]() ![]() 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. Here are a few examples of the data visualization and rapid reaction profiling on a 60 MHz 1H NMR series obtained every 10 seconds (1 pulse) over the course of 25 minutes – the reaction is the esterification of tert-butanol with acetic anhydride in the presence of acid.įigure 1: Stacked Plot of the Aliphatic Region of the Spectrum with Reaction Chemistry Protons Identifiedįigure 2: Stacked Plot – Full Spectrum – Reaction Monitoring – 146 Spectra – 10 Seconds Apartįigure 3: Angled Stack Plot – Acetic Anhydride and tert-Butanol – Real Time Reaction Monitoring by 1H NMR at 60 MHzįigure 4: Stacked and Whitewashed Plot of 1H NMR data at 60 MHz – Real Time Reaction Monitoring of Acetic Anhydride with tert-Butanolįigure 5: Data Analysis Tool and production of reaction profiles. Further steps allow the exponential fitting of the reaction profiles to yield kinetic information. The data analysis capabilities of the MestReNova NMR software makes processing and analyzing complex reaction mixture data a snap! Stacked plots are quick and easy and the integration routines rapidly process the peak areas into reaction profiles. ![]()
