## Fit data NMR

Hello, I didn't know where else to post this so here it goes ...

I have collected data from a pulsed NMR experiment to calculate the value of the spin-lattice relaxation time (T1). Now I'm asked to fit the data using a function of the form
V(t) = V_0*(1 - 2*exp(-t/T1)). But I'm not really sure how to fit it. Is there any software out there I can use to fit this data with that function? I was trying to fit it using ROOT but I did not succeed ;(.
