*Addendum to the data below;

*Abstract, Before continuing any further in phase II testing, I wanted to see just where I am in both optical resolution and spatial resolving power. So I decided to take some spectral data from an EVOO sample I've had for awhile (preserved in a plastic UV cuvette W/an air tight top,) it's about 4 months old and some degradation does show up in the data but it was still an excellent sample to use.

The methodology that I am using for this project may seem slow but it's purpose is both methodical and purposeful, in that, every small successful step brings the entire project closer to its main objective, which is, Raman spectroscopy in the 532nm range. Phase III begins when I feel confident enough in the data that, both instrumentally and methodology are sufficient for Raman spectroscopy.

The plot below is the "raw" data:
