The molecular structure of ferrocene

The Journal of Chemical Physics, 1996
The vertical iron–cyclopentadienyl distance in ferrocene has been determined using ab initio coupled-cluster theory. At the CCSD level, a TZV2P basis set yields a metal–ligand distance of 1.664 Å with all 96 electrons correlated and 1.672 Å with 66 electrons correlated. With 66 electrons correlated at the CCSD(T) level the equilibrium distance is 1.660

Wavelets and molecular structure

Journal of Computer-Aided Molecular Design, 1996
The wavelet method offers possibilities for display, editing, and topological comparison of proteins at a user-specified level of detail. Wavelets are a mathematical tool that first found application in signal processing. The multiresolution analysis of a signal via wavelets provides a hierarchical series of "best' lower-resolution approximations.

Twisted Molecular Structure on Tuning Ultralong Organic Phosphorescence.

Journal of Physical Chemistry Letters, 2018
Compared to planar carbazole, the molecular conjugation of iminodibenzyl (Id) was destroyed by a C-C bond and a twisted structure was formed, which exhibited blue-shifted ultralong phosphorescence with a lifetime of 402 ms in a crystal under ambient ...

Atomic Force Microscopy for Molecular Structure Elucidation.

Angewandte Chemie, 2018
Using scanning probe microscopy techniques, at low temperatures and in ultrahigh vacuum, individual molecules adsorbed on surfaces can be probed with ultrahigh resolution to determine their structure and details of their conformation, configuration ...

On the Molecular Structure of Collagen

Nature, 1969
Several polytripeptide and polyhexapeptide models of collagen have the same triple helical conformation with one NH…O interchain H bond per tripeptide. Collagen itself probably has this structure.

Occurrence State and Molecular Structure Analysis of Extracellular Proteins with Implications on the Dewaterability of Waste-Activated Sludge.

Environmental Science and Technology, 2017
The occurrence state and molecular structure of extracellular proteins were analyzed to reveal the influencing factors on the water-holding capacities of protein-like substances in waste-activated sludge (WAS).

Nephrotoxicity and Molecular Structure

Xenobiotica, 1975
The nephrotoxicity of a number of aminophenols, quinols and catechols has been assessed from the extent of necrosis of proximal convoluted tubules produced by intravenous injection in rats, and the toxicity correlated with the oxidation-reduction potentials of the compounds.

Molecular Structure of Proline

Chemistry – A European Journal, 2004
AbstractThe molecular structures of the two lowest‐energy conformers of proline, Pro‐I and Pro‐II, have been characterized by ab initio electronic structure computations. An extensive MP2/6‐31G* quartic force field for Pro‐I, containing 62 835 unique elements in the internal coordinate space, was computed to account for anharmonic vibrational effects ...
