Raman spectroscopy as a tool to the in situ study of three lichens species from Antarctica and Brazil
In this investigation the chemistry of the lichens Gondwania regalis , Teloschistes exilis and Xanthoria candelaria ( Teloschistaceae ) have been recorded by means of Raman spectroscopy. The non‐destructive analysis provided the recognition of parietin and conjugated polyenes, probably belonging to...
