We present the model for preeqmhbnum statistical ((S(E)',/ = 01 reactmns where the S-matnx elements v.qth d,fferent spm-xalues are correlated. In th~s model t~me-dcla)ed d,ffcrcnttal cross-scctmns have the form of classical diffusion processes m time-scaucrmg-angle space As a consequence the energ) autocorrelat~on function of fluctuating cross-scctmns does not have Lorenman angle-independent sh...

Prisms and slabs made of high-refractive-index materials such as ZnSe, Ge, and Si can be designed as broadband, 50%-50%, beam splitters (BSs) for obliquely incident s- polarized light in the near- and mid-IR. The beam-splitting face of the prism or slab is uncoated, while the exit face is antireflection coated. The split beams travel in orthogonal directions when light is incident at the Brewst...

As highly sensitive H2S gas sensors, Au- and Ag-catalyzed SnO2 thin films with morphology-controlled nanostructures were fabricated by using e-beam evaporation in combination with the glancing angle deposition (GAD) technique. After annealing at 500 °C for 40 h, the sensors showed a polycrystalline phase with a porous, tilted columnar nanostructure. The gas sensitivities (S = Rgas/Rair) of Au a...

The title mol-ecule, C(15)H(16)N(2)O(3)S, has a twisted U-shaped conformation. The twist occurs in the central C-S(=O)(2)N(H)-C unit with the C-S-N-C torsion angle being -58.38 (14)°. The benzene rings lie to the same side of the mol-ecule and form a dihedral angle of 67.03 (10)°. The crystal packing features N-H⋯O hydrogen bonding, which leads to supra-molecular chains with a tubular topology ...

In the crystal structure of the title compound, C(15)H(17)NO(2)S, the conformation of the N-C bond in the C-SO(2)-NH-C segment has gauche torsions with respect to the S=O bonds. The mol-ecule is bent at the S atom with a C-SO(2)-NH-C torsion angle of -61.0 (2)°. The dihedral angle between the two aromatic rings is 49.4 (1)°. The crystal structure features inversion-related dimers linked by pair...

In the asymmetric unit of the title compound, C(16)H(11)FO(5)S, the 2H-chromene ring is essentially planar, with a maximum deviation of 0.040 (2) Å. The dihedral angle between the 2H-chromene ring and the 4-fluoro-phenyl ring is 2.17 (8)°. One of the sulfonamide O atoms is approximately coplanar with the benzene ring [C-C-S-O torsion angle = 166.00 (14)°], whereas the other O atom lies well bel...

The title Schiff base compound, C(13)H(11)N(3)O(5)S, exists in an E configuration with respect to the C=N double bond. The benzene rings are almost coplanar, making a dihedral angle of 2.82 (6). The sulfonamide group is twisted away from the attached phenyl ring with an N-S-C-C torsion angle of 64.84 (11)°. An intra-molecular O-H⋯N hydrogen bond stabilizes the mol-ecule, generating an S(6) ring...

In the crystal of the title compound, C(13)H(12)N(2)O(4)S, the conformation of the N-H bond in the -SO(2)-NH- segment is syn to the ortho-nitro group in the sulfonyl benzene ring. The mol-ecule is twisted at the S-N bond with a torsion angle of 76.55 (18)°. The dihedral angle between the planes of the rings is 72.64 (8)°. In the crystal, mol-ecules are linked by pairs of N-H⋯O(S) hydrogen bonds...

In the title salt, (C(13)H(10)N(3)O(2))[Ni(C(3)S(5))(2)], the Ni(III) cation is S,S'-chelated by two 2-thioxo-1,3-dithiole-4,5-dithiol-ate anions in a distorted square-planar geometry. The complex anion is approximately planar with a maximum deviation of 0.097 (1) Å. In the 1-(4-nitro-benz-yl)-4-cyano-pyridinium cation, the pyridine ring is twisted at a dihedral angle of 73.84 (16)° with respec...

The title compound, C12H9BrN2OS2, was obtained by reacting 6-bromo-benzo[d]thia-zole-2-carbo-nitrile in iso-propanol with ethyl 2-mercapto-2-methyl-propano-ate at reflux temperature for several hours. The resulting di-methyl-oxyluciferin derivative shows partial double-bond character of the carbon-carbon bond between the two heterocyclic moieties [C-C = 1.461 (3) Å]. This double bond restricts ...
