Reflection nebular spectra and the rise of the Savanna 30Ma ago
Bob Fosbury


Most likely PAH identifications are with anthracene and pyrene -- which both have a very high fluorescent efficiency for near-UV excitation Technique useful for specific PAH size determination and identification -- not possible with the IR bands


Comparison of blue amber and reflection nebula (Ced 201) fluorescence PAH from forest fire smoke, probably captured by sap from the now extinct tree Hymenaea protera ~ 25 million years ago when the grasses were stealing land from the forests (low CO2, high O2)
