The molecular composition and structure of a given substance do not depend on the method of preparation used. In the case of monatomic molecules (for example, inert gases), the concepts of the molecule and the atom are congruent. The concept of the molecule was first introduced into chemistry...
In the sulfido clusters, sulfur plays important roles as a good electron donor and as a bridging element to fix the multimetallic structure. Moreover, sulfur atoms often interact with substrate molecules and can participate in molecular conversion as the reaction sites. From a different point of ...
View Solution Which of the following species have intra molecular H-bonds? View Solution Assertion B2 molecule is diamagnetic Reasoning The highest occupied molecular orbital is of sigma type . View Solution Which of the following is the Lewis structure of O2 molecule? View Solution ...
Proteins are the building blocks of all life forms on Earth. Proteins are polymeric molecules that are formed by the bonding between several monomeric units or molecules. In proteins, amino acids combine to form the final complex polymeric protein structure. The DNA of each cell encodes amino aci...
Hemoglobin structure in a detailed, interactive and illustrated tutorial with colorful and simple animations about its states (relaxed & tensed).
Laser-ablated Hf atoms react with H2O2 and with H2 + O2 mixtures in solid argon to form the Hf(OH)2 and Hf(OH)4 molecules, which are identified from the effect of isotopic substitution on the matrix infrared spectra. Electronic structure calculations at the MP2 level varying all bond leng...
matter. Substances differ according to the structure and composition of their molecules. A molecular compound is represented by its molecularformula; for example, water is represented by the formula H2O. A more complex structural formula is sometimes used to show the arrangement of atoms in the ...
2a). Co-crystals of a quaternary complex of PolθΔL bound to a DNA/DNA primer-template, RTx-161 and incoming ddGTP did not diffract well. As an alternative approach, we solved the quaternary structure of PolθΔL bound to the closely related analog RTx-152 (Fig. 3a). We conducted ...
