Poly(3,4-ethylenedioxythiophene) (PEDOT) films doped with nitric and chlorine ions have been electrochemically deposited simply by a one-step electrochemical method in an aqueous media in the absence of any surfactant. The fabricated PEDOT films were characterized by scanning electron microscopy, transmission electron microscopy, and Raman spectroscopy. The results indicate that the hierarchica...

We study the effect of counter-ion complexation on the example of Cl(-) ions interacting with the [Co(en)(3)](3+) complex. The H-bonding of the N-H groups of the ethylenediamine (en) ligands with the Cl(-) ions may lead to giant enhancement of the VCD intensity for the N-H stretches, but may also lead to VCD sign changes in the finger print region of N-H wagging, twisting and scissoring motions...

Electrospray ionization produces phenylalanine (Phe) complexes of the alkali metal ion series, plus Ag(+) and Ba(2+). Infrared multiple photon dissociation (IRMPD) spectroscopy using the FELIX free electron laser light source is used to characterize the conformations of the ions, in conjunction with density functional theory (DFT) calculations giving thermochemical information and computed infr...

Mass spectrometry and ion chemistry of alkylbenzenes, today, is much more than the gas-phase reactions of their radical cations and their prominent fragment ions, such as C7H7+ and C7Hs+'. Indeed, the gas-phase chemistry of gaseous ions originating mainly from the electron impact (EI) ionization of alkylbenzenes has been investigated extensively for more than 35 years and has revealed to us num...

Submit Manuscript | http://medcraveonline.com electromagnetic wave was firstly shown by Oleinik [4]. However, the theoretical proof of the attraction possibility was given by Kazantsev and Sokolov for interaction of classical relativistic electrons in the field of a plane wave [5]. It is worth noting the work [6]. It is very important to point out, that attraction of classical electrons in the ...

Investigations into the effects of the choice of anion on the hydrogen-bonding interactions between anions and metal-sulfimide cationic complexes have led to the study of three novel compounds. Hexakis(S,S-diphenylsulfimide)cobalt(II) diiodide S,S-diphenylsulfimide acetonitrile disolvate, [Co(C12H11NS)6]I2.C12H11NS.2C2H3N, crystallizes in the centrosymmetric space group P-1 with Z = 2. Six diph...

Gas phase fragmentation of hydrogen deficient peptide radical cations continues to be an active area of research. While collision induced dissociation (CID) of singly charged species is widely examined, dissociation channels of singly and multiply charged radical cations in infrared multiphoton dissociation (IRMPD) and electron induced dissociation (EID) have not been, so far, investigated. Her...

Condensation of aromatic aldehydes with benzoyl acetone under specified conditions yieldedtwo series of polycarbonyl compounds in which the keto group is attached to olefinic linkage.Spectral and analytical data revealed the formation of an unsaturated triketone from pyridine-3-carbaldehyde and unsaturated diketone from furfural, salicylaldehyde and 2-hydroxynaphthaldehyde. Analytical, IR, 1H N...

Quantum mechanical ab initio UHF, MP2, MC-SCF and DFT calculations with moderate Gaussian basis sets were performed for MnX6, X = H2O, F, CN, manganese octahedral complexes. The correct spin-state of the complexes was obtained only when the counter ions neutralizing the entire complexes were used in the modelling at the B3LYP level of theory.

In the title complex salt, [{(η(5)-C5Me5)Rh}2(μ-Cl)3]PF6, the dinuclear, single-charged cation is formed by the cojoining of two classic (η(5)-C5Me5)RhCl3 'piano-stool' units by bridging of the three choride ligand 'legs'. The crystal structure shows several close H⋯F contacts between the hexa-fluorido-phosphate counter-ions and the C5Me5 ligands.
