Ohmic Spectral Density Fitting Issue

[juan0603-chem]

Dear Qutip Group,
I hope you are doing well.

I'm trying to implement the fitting of a ohmic spectral density with exponential cutoff, and the example works pretty well, however when I change the parameters to the ones I need, it fails

T = T = 3e10 * 2 * np.pi *300*0.6949 # temperature wc = 1750 *3e10 * 2 * np.pi beta = 1 / T s = 1

I'm just using this parameters and I obtain a plot like this:

What Im doing is changing from cm-1 to Hz as in the FMO complex notebook.

Could you please help me?
