(yet another) UV-VIS query. Today: Yellow. - Subhan - 04-12-2018

Hello again. 


I've got a uv-vis spectrogram of a yellow coloured solution. What I'm having difficulty with is that there is no lambda max peak to help me work out the frequency: it's just a steady slope very similar to this one: www.trinity.edu/fwalmsle/MandMPictures/YellowDyeSpectrum.bmp

I'm not sure how to interpret this. I am inclined to suppose that there is just an increasing absorbance of wavelengths, and that if I were to extrapolate the graph back into the UV I might eventually get a peak to use in calculations of frequency, but I don't know.

What should I do? Any worthwhile reference material that I can read up on this specific issue? The handful of books I've got aren't helpful.

Thanks a million.
