The Bellfit program fits and plots bell shaped pH data to the following equation:
kobs = k/(1+[H]/K2+K1/[H])
The results can be printed, saved as a text document or copied and pasted into other OpenOffice files.
When Fit is selected a linear reciprocal plot is used to make the initial estimates of kobs and the pKa. These values of kobs and pKa are then used as the initial estimates to fit the experimental data using an iterative, non linear least-squares regression program.
When Fit with estimates is selected you must input the initial estimates of kobs and the pKa. The experimental data is then fitted using an iterative, non linear least-squares regression program.
NOTE: Bellfit can only be purchased via the Mac App Store (the buy link redirects you to its App Store page). To purchase/download applications via the App Store an Apple account is required.
