Substituted naphthalene nomenclature

WebDecalin is the saturated analog of naphthalene and can be prepared from it by hydrogenation in the presence of a catalyst. This interconversion has been considered in the context of hydrogen storage. [6] Occurrence [ edit] Decalin itself is rare in nature but several decalin derivatives are known. WebSubstituted naphthalene anions (deprotonated 2-naphthol and 6-hydroxy-2-naphthoic acid) are spectroscopically probed in a tandem drift tube ion mobility spectrometer (IMS). Target anions are selected according to their drift speed through nitrogen buffer gas in the first IMS stage before being exposed to a p Advances in ion spectroscopy - from astrophysics to …
