No clue. Went to PubMed and searched for "pollen spectra". Found http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4395086/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4395086/ from PLoS One, 2015 Apr 13: > Aeroallergen monitoring networks are an important part of treatment strategies, but unfortunately traditional analysis is time consuming and expensive. We have explored the use of infrared spectroscopy of pollen and spores for an inexpensive and rapid characterization of aeroallergens. They think it's doable.
