Absorption and Emission plot for Rhodamine B in Ethanol, using a Solux 4700K 50W 12vdc lamp for absorption measurements and a 150mW 532nm Green laser for fluorescence measurements;

Next, is the absorption plot for all 3 Rhodamine B scans (raw data,) scan 3,4 and 5. Scan 3 was chosen because it had the closest molar absorption coefficient match to the reference spectrum (OMLC,Oregon Medical Laser Center's scan of the same compound-Rhodamine B in Ethanol.)
