Often times, you can research the chemical composition of odors by searching for its name plus GCMS. The Good Scent Company is a free online database of natural materials, pure aromachemicals, and formulae. Issues of the trade rag Perfumer & Flavorist are available for free online and there will be content about GCMS, chemistry, and formulating. Basenotes is a forum for amateur perfumery that may have relevant conversation. And there are the manufacturers of chemicals used in fragrance and flavors: Givaudan, IFF, Firmenich, Symrise, and others. Their catalogues and the vendors that sell them (some even in small quantities) can be valuable resources just for exploring the space.
