Hello all,
I want to ask if it is possible to find the rate of decay for a curves at different temperature (picture attached) using fitting function in origin.


Please help me chosing a fitting function and the most important thing is to know the rate of change from the function.

Hi,

There are some built-in fitting functions for exponential decay in Origin, you may find them under the Exponential category. From these functions you will get the time constant of decay as one fitting parameter and the time constant should be the reciprocal of the decay rate.



If the general exponential decay functions do not fit with your data well, you could also define your own fitting functions and use them from the Nonlinear Curve Fit tool in Origin.
