Speciation of organosulfur compounds in carbonaceous chondrites

Abstract Despite broad application of different analytical techniques for studies on organic matter of chondrite meteorites, information about composition and structure of individual compounds is still very limited due to extreme molecular diversity of extraterrestrial organic matter. Here we presen...
