A chemical ionization source from mass spectrometry was modified for matrix isolation spectroscopic studies. Argon positive ion chemical ionization of naphthalene produced naphthalene cation based on agreement of the matrix electronic spectrum with that obtained by vacuum ultraviolet radiation and electron impact techniques. Negative ion studies with chlorine gave the Cl2− and Cl3− anion absorptions at 340 and 253 nm, respectively, whose relative intensities depended on source pressure. Furthermore, Cl2/HCl/Ar chemical ionization produced mainly HCl2− anion absorbing at 287 nm due to secondary ion processes occurring inside the source block.

A thiazolothiazole containing multichromic polymer for glucose detection Soylemez, S.; Kaya, H. Z.; Udum, Y. A.; Toppare, Levent Kamil (Department of Polymer Engineering, Scientific Society of Mechanical Engineering, 2019-10-01) Donor-acceptor (DA) type monomers namely 2,5-di(thiophen-2-yl)thiazolo[5,4-d]thiazole (TTzTh) and 2,5-bis(3-methylthiophen-2-yl)thiazolo[5,4-d]thiazole (TTzMTh) were synthesized and their electrochemical and optoelectronic properties were investigated in detail. The spectro-electrochemical analysis showed that the alkyl chain substitution results in a shift in the onset of the pi-pi* transition towards longer wavelengths. Depending on the donor substituents, the polymers exhibited optical band gaps 1.65 and...
A new and efficient chemoenzymatic route to both enantiomers of alpha '-acetoxy-alpha-methyl and gamma-hydroxy-alpha-methyl cyclic enones Demir, Ayhan Sıtkı; Findik, H; Kose, E (Elsevier BV, 2004-03-08) A chemoenzymatic synthesis of both enantiomers of the pharmacologically interesting alpha'-acetoxy-alpha-methyl and gamma-hydroxy-alpha-methyl cyclic enones starting from alpha-methyl-beta-methoxy cyclic enones is reported. Manganese(Ill) acetate-mediated acetoxylation followed by the enzyme-mediated hydrolysis of alpha'-acetoxy enone provides acetoxy enones 1a and 2a and hydroxy enones 1b and 2b with high enantiomeric excesses in good yields. The reduction of the acetoxy and hydroxy enones furnished both e...
A theoretical study on the simplest fullerene, C-20 - an AM1 treatment Türker, Burhan Lemi (Elsevier BV, 2003-05-05) Within the constraints of AM1 (UHF) type semiempirical quantum chemical treatment, C-20 and its cationic and anionic forms were considered for their stabilities. The results revealed that C-20 has a greater tendency to act as electron acceptor than a donor. C-20(-) and C-20(-2) were found to be even more stable than C-20.
A perturbative treatment for the energy levels of neutral atoms Ikhdair, Sameer M.; Sever, Ramazan (World Scientific Pub Co Pte Lt, 2006-12-20) Energy levels of neutral atoms have been reexamined by applying an alternative perturbative scheme in solving the Schrodinger equation for the Yukawa potential model with a modified screening parameter. The predicted shell binding energies axe found to be quite accurate over the entire range of the atomic number Z up to 84 and compare very well with those obtained within the framework of hypervirial-Pade scheme and the method of shifted large-N expansion. It is observed that the new perturbative method may ...
The valence electronic structure and conformational flexibility of epichlorohydrin Stranges, S.; Alagia, M.; Decleva, P.; Stener, M.; Fronzoni, G.; Toffolı, Danıele; Speranza, M.; Catone, D.; Turchini, S.; Prosperi, T.; Zema, N.; Contini, G.; Keheyan, Y. (Royal Society of Chemistry (RSC), 2011-01-01) The electronic structure of epichlorohydrin is investigated in the whole valence region by a combined experimental and theoretical study. The issue of controversial assignments of the molecular electronic structure is here addressed. Photoelectron spectra (PES) and Threshold Photoelectron spectra (TPES) of room temperature molecules in the gas phase are recorded. Geometries and energies of the stable conformers due to internal rotation of the C-C-C-Cl dihedral angle, gauche-II (g-II), gauche-I (g-I), and ci...
