Abstract

The femtosecond pump-probe transient absorption spectroscopy is used to measure the ultrafast time-resolved electronic spectra of primary events induced in copper tetrasulfonated phthalocyanine Cu[(tsPc).sup.4-]) in aqueous solution. Combining of spectroscopy and electrochemical measurements gives clear interpretation of primary events upon light excitation, photochemical mechanisms and spectral features relating to photophysical and photochemical mechanisms.

Abstract

The structure and energetics of the simplest vic-disulfoxide CH3S(O)S(O)CH3 and its key isomers are reported. The B3LYP structure obtained for 5,5-di-t-butyltetrathiolane-2, 3-dioxide reproduces the essential structural parameters of the known vic-disulfinyl compound, 5-(1-adamantyl)-5-tert-butyltetrathiolane-2,3-dioxide.

Abstract

Relative rate methods are used for rate constants for the gas-phase reactions of divinyl sulfoxide (DVSO) with N[O.sub.3] radicals and [O.sub.3] and rate constants for the reaction with OH radicals are measured. The results obtained for the DVSO are compared for the corresponding reactions of dimethyl sulfoxide.

Abstract

Thioester molecules, S-methyl thioacetate, C[H.sub.3]C(O)SC[H.sub.3], are examined by HeI photoelectron spectroscopy (PES) and valence photoionization studies by using synchrotron radiation in the same energy range. The photodissociation behavior of C[H.sub.3]C(O)SC[H.sub.3] is divided into three well-defined energy regions and vibronic structure is seen in the valence synchrotron photoionization process.

Abstract

The electron-diffraction techniques complemented by theoretical methods were used determine the gas phase molecular structure of methyl methanethiosulfonate, C[H.sub.3]S[O.sub.2]SC[H.sub.3]. The formation of both anti and gauche conformer is possible by rotating about S-S bond, but the gauche conformer is found to be more stable.

Abstract

Several different computational approaches such as G3MP2B3, G3, B3LYP and CBS-Q were used to compute the gas-phase enthalpies of formation of small sulfur-containing molecules. The different computational schemes are tested in order to know which yields the best results when compared with experimental data.
