Photolysis of Dimethyl Sulfide

Di-μ-chlorido-μ-(dimethyl sulfide)-bis­{dichlorido[(dimethyl selenide-κSe)(dimethyl sulfide-κS)(0.65/0.35)]niobium(III)}(Nb—Nb)

The dinuclear compound, [Nb(2)Cl(6)(C(2)H(6)S)(1.7)(C(2)H(6)Se)(1.3)], features an Nb(III)=Nb(III) double bond [2.6878 (5) Å]. The mol-ecule lies on a twofold rotation axis that passes through the middle of this bond as well as through the bridging dimethyl sulfide ligand. The Nb(III) ion exists in an octa-hedral coordination environment defined by two terminal and two bridging Cl atoms, and (C...

Title Some Observations on the Photolysis of Dimethyl Disulfide

Dimethyl sulfide triggers search behavior in copepods

The oceans are nutritionally dilute, and finding food is a major challenge for many zooplanktonic predators. Chemodetection is necessary for successful preycapture, but little is known about the infochemicals involved in the interaction between herbivorous copepods and their phytoplankton prey. We used females of Temora longicornis to investigate chemodetection of dimethyl sulfide (DMS) in this...

Comparison of global climatological maps of sea surface dimethyl sulfide

[1] We have examined differences in regional and seasonal variability among seven global climatologies of sea-surface dimethyl sulfide (DMS) concentrations. We found large differences between recent climatologies and that typically used by most atmospheric sulfur models. The relative uncertainty (1s/mean) in the latitudinal distribution of the annual mean DMS concentration increases from about ...

Formation of dimethyl sulfide and methanethiol in anoxic freshwater sediments.

Concentrations of volatile organic sulfur compounds (VOSC) were measured in water and sediment columns of ditches in a minerotrophic peatland in The Netherlands. VOSC, with methanethiol (4 to 40 nM) as the major compound, appeared to be mainly of sediment origin. Both VOSC and hydrogen sulfide concentrations decreased dramatically towards the water surface. High methanethiol and high dimethyl s...
