Organic molecules ranges

In the MOE environment, molecules are stored in a database with their associated set of conformations. Several methods can be applied to expand the conformational space of organic molecules ranging from molecular dynamics to stochastic methods and systematic search. A fragment-based high-throughput... 

In fact, it has been found that organic molecules range from such simple ones as CH (methane), GH O (formaldehyde), HgCgOi (oxalic acid), through those of increasing complexity, such as (cane sugar), C2iH 0 N ... 

In principle, there is no limit to the number of carbon atoms that can bond covalently. Thus, organic molecules range from the simple molecules such as methane (CH4) to very complicated molecules containing over a million carbon atoms. 

One of the interesting fundamental questions associated with a nanoporous material concerns the effect of the nanopore on the structure and associated properties of a loaded or infiltrated substance. For the case of pSi films still attached to its underlying Si substrate, this question has been addressed for a range of simple organic molecules, ranging from alkanes (such as hexane (Henschel et al. 2009)) to alcohols of various sizes (from as small as ethanol (Henschel et al. 2010) to a 19 carbon linear chain alcohol (Henschel et al. 2008 Berwanger et al. 2009)). In such studies, the size of the pore clearly has a strong influence on the structure of the infiltrated species. For... 

The MM2, MM3, and Merck (MMFF) force fields perform best for a wide range of organic molecules. 

Nitrogen, unlike pyritic sulfur, is mosdy chemically bound in organic molecules in the coal and therefore not removable by physical cleaning methods. The nitrogen content in most U.S. coals ranges from 0.5—2.0 wt %. 

Hydrolysis. The general process definition for hydrolysis embraces all double-decomposition reactions between water (usually ia the form of acid or alkah solutions of a wide range of strengths) and an organic molecule. 

Matrix-assisted laser desorption/ionization (MALDI) is widely used for the detection of organic molecules. One of the limitations of the method is a strong matrix background in low-mass (up to 500-700 Da) range. In present work an alternative approach based on the application of rough matrix-less surfaces and known as surface-assisted laser desoi ption/ionization (SALDI), has been applied.
