Synthesis, structure, and spectroscopic properties of copper(II) compounds containing nitrogen–sulphur donor ligands; the crystal and molecular structure of aqua[1,7-bis(N-methylbenzimidazol-2′-yl)-2,6-dithiaheptane]copper(II) perchlorate

, 1984
The linear quadridentate N2S2 donor ligand 1,7-bis(N-methylbenzimidazol-2′-yl)-2,6-dithiaheptane (bmdhp) forms mono- and di-hydrate 1 : 1 copper(II) complexes which are significantly more stable toward autoreduction than those of the non-methylated ...

Massively Evoking Immunogenic Cell Death by Focused Mitochondrial Oxidative Stress using an AIE Luminogen with a Twisted Molecular Structure

Advances in Materials, 2019
Immunogenic cell death (ICD) provides momentous theoretical principle for modern cancer immunotherapy. However, the currently available ICD inducers are still very limited and photosensitizer‐based ones can hardly induce sufficient ICD to achieve ...

Molecular Structure of LSD

Science, 1972
The molecular configuration of lysergic acid diethylamide (LSD) in crystals of the iodobenzoate has been determined by using x-ray diffraction techniques. The configuration shows strain and steric hindrance and the conformation is fixed. Some of the implications of this for the hallucinogenic activity of LSD are discussed.

Molecular Structure and Formation Mechanism of Hydrochar from Hydrothermal Carbonization of Carbohydrates

Energy & Fuels, 2019
Hydrochars are solid byproducts formed during the liquid-phase biorefinery process and could be used to generate functional carbonaceous materials, but the detailed molecular structure and the form...

Molecular Structure of Thiourea

The Journal of Physical Chemistry A, 2012
The molecular structure of thiourea has been investigated under C(s), C(2), and C(2v) symmetry constraints. At the coupled-cluster level in conjunction with a triple-ζ basis set, only the C(2) conformer has been found to be a real minimum on the potential energy surface.

Structure of molecular liquids

Physical Review E, 1995
We present a method for calculating, by computer simulation, the direct correlation function c(1,2) for a molecular liquid in the form of a spherical harmonic expansion. This allows us to test, at the most fundamental level, predictions of the structure of molecular liquids using density functional and integral equation approaches.

Molecular structure of nucleic acids : a structure for deoxyribose nucleic acid

, 1993
WE wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A.). This structure has novel features which are of considerable biological interest. A structure for nucleic acid has already been proposed by Pauling and Corey1.

The molecular structure of collagen

Journal of Molecular Biology, 1961
This paper describes in detail our work on the structure of collagen which we have already outlined elsewhere ( Rich & Crick, 1955 ). The main substance of the paper is: (1) a demonstration that, given certain assumptions, only two basic types of structures are possible for collagen; (2) detailed work on the coordinates and Fourier ...

Black Carbon (Biochar) In Water/Soil Environments: Molecular Structure, Sorption, Stability, and Potential Risk.

Environmental Science and Technology, 2017
Black carbon (BC) is ubiquitous in the environments and participates in various biogeochemical processes. Both positive and negative effects of BC (especially biochar) on the ecosystem have been identified, which are mainly derived from its diverse ...

On the molecular structure of HOOO

The Journal of Chemical Physics, 2012
The molecular structure of trans, planar hydridotrioxygen (HOOO) has been examined by means of isotopic spectroscopy using Fourier transform microwave as well as microwave-millimeter-wave double resonance techniques, and high-level coupled cluster quantum-chemical calculations.
