Python 3 - decode spectroscopy data (Base64, IEEE754)

Question

I'm a chemist and working with spectroscopic data that was stored as a list (501 pairs of X,Y data) of Base64-encoded floating point values according to IEEE754.

I tried to get an array of X, Y data to work with from the raw data but failed. Attached is the raw data of a spectrum.

May I please ask for your guidance/help on this topic? I'm lost, Chris
