Alright, I added old spice to the toluene. There is MASSIVE fluorescence spetrum . There are small waves in said comtinuum. I hope that by subtracting/analyzing the fluorescence out, the toluene spectrum and (hopefully) a DMT spectrum will arise. Any tips for doing this? For now I'll be reading benzyne's resources he posted and be trying to fit the fluorescence to some kind of function, treating the residual of the fit as the signal.

Below is the image of the fluorescence and raw data in CVS format (along with a calculated raman shift).

On the plus side, I recentered the spectrometer and can see further into the red. The equations from the previous post were useful (I used the toluene peaks, including two new ones that appeared at higher Raman shift to calibrate). I decreased the angle of the diffraction grid and the focusing mirror. The equation fit well and I got 6 degrees and 10 degrees for those angles respectively (was shooting for 3 and 14 but it is difficult to control). With this setup I still have 100% theoretical light up to pixel 1300 or so.

Fell free to analyze the data. Can anyone recover toluene peaks (they should be there)? What about a DMT signal (or oxide DMT)?

I may also consider getting an short-pass filer and check on the anti-stokes radiation, cause this fluorescence is crazy.

Many thanks.
