Caveat: This forum is for help on the core Python language
and its standard library. Asking about anything beyond that
may require a lot more information about the context - for
example few of us will know anything about UV/VIS spectra
(even what that means!)

However, I'll hazard a guess...

> figure = name+'.png'
> print(figure)
> plt.savefig('figure', bbox_inches='tight')

Shouldn't the last line use the variable figure
rather than a literal string 'figure' :

plt.savefig(figure, bbox_inches='tight')

I'm guessing that's because you are passing the string 'figure'
instead of the variable.

But I don;t know anything about your plt object
or its savefig() method, not even which library
you are using. Is it matplotlib? Or something else?
