Chemistry graduates have much scope to use their knowledge in a range of research sectors, including roles within chemical engineering, chemical and related industries, healthcare and more. Formula: https://www.ambeed.com/products/85-61-0.html85-61-0, Name is Coenzyme A, SMILES is CC(COP(O)(OP(O)(OC[C@](O1)([H])[C@](OP(O)(O)=O)([H])[C@](O)([H])[C@]1([H])N2C=NC(C2=NC=N3)=C3N)=O)=O)(C(O)([H])/C(O)=N/CC/C(O)=N/CCS)C, belongs to dioxole compound. In a article, author is GLEITER, R, introduce new discover of the category.

The six donor-acceptor spiro compounds spiro[1,3-dioxolane-2,2′-indan]-1′,3′-dione (8), spiro[indan-2,2′-[1,3]oxathiolane]-1,3-dione (9), spiro[1,3-dithiolane-2,2′-indan]-1′,3′-dione (10), spiro[1,3-benzodioxole-2,2′-indan]-1′,3′-dione (11), 5-methylspiro[1,3-benzodithiole-2,2′-indan]-1′,3′-dione (12), and spiro[indan-2,2′-naphtho[2,3-d]-1,3-dioxole]-1,3-dione (13) have been prepared. Their He(I) photoelectron spectra and their UV/Vis spectra have been investigated. A comparison between the first PE bands of the spiro compounds and the corresponding fragments indicates only a very weak interaction between both parts. The UV/Vis spectra of 11-13 show a moderate long-wavelength shift of the first band as compared to 1,3-indandione. This band is assigned to a transition from the HOMO(pi), localized at the donor fragment, to the LUMO(pi*) of the acceptor moiety (charge transfer). X-ray investigations of 8-10 and 13 show no interaction between the two perpendicularly arranged moieties.
