Aproximating a morse potential using a taylor polynomial
I am not going to post my question because I want to find out how to actually use the taylor polynomial and morse potential and then apply that to my problem. Say I have to approximate the morse potential using a taylor series expanding about some value. This will then find me the force constant. How would I go about setting up such equations?

f(x) = f(a) + f'(a)(xa) + f''(a)/2! (xa)^2 and so on I'm not sure how to do this on a morse potential. Seems like there are a lot of variables and I'm not sure from my given data, what goes where.
