Visualization of molecular

To recognize which programs can be used for graphical input and visualization of molecular structures... 

Two successful and widespread appHcations of visualization techniques in the field of chemistry are the visualization of molecular orbitals and the visualization of molecules in molecular mechanics studies. 

Fortunately, it was found that in polypeptide systems the effective dimensionality of conformational spaces is significantly smaller than the dimensionality of the full space, with only a few principal axes contributing to the projection [38-41]. In fact, in many cases a projection quality of 70-90% can be achieved in as few as tliree dimensions [42], opening the way for real 3D visualization of molecular conformational space. Figure 8...

Figure 5.4 Visualization of molecular fragments using a lasso tool. The lasso tool is used to identify a particular fragment, and if a signal corresponding to its mass is present in the spectrum, the fragment is highlighted and the corresponding assignment is added to an assignment table.

Very striking results on the interactions of molecules with a catalyst have been recently reported in zeolite catalysis because of the well ordered structure of these materials it is worth mentioning the subjects of zeolite design [10] and of acidic properties of metallosilicates [11]. In other areas where polycrystallinic or even amorphous materials arc applied, highly interesting results are now numerously emerging (such as hydrocarbon oxidation on vanadium-based catalysts [12] location of transition metal cations on Si(100) [13] CO molecules on MgO surfaces [14] CH4 and O2 interaction with sodium- and zinc-doped CaO surfaces [15] CO and NO on heavy metal surfaces [16]). An illustration of the computerized visualization of molecular dynamics of Pd clusters on MgO(lOO) and on a three-dimensional trajectory of Ar in Na mordenitc, is the recent publication of Miura et al. [17]. 

The visualization of molecular structures finds a home in this realm. Using packages such as TRIBBLE (DuPont) or the PHOPHET system (Bolt Baranek Newman, Cambridge, Mass.) one can describe a molecular structure and have the system display the three-dimensional structure as it would appear when viewed from various reference points.

An alternative approach to the rationalization of reactivity patterns, involving the three-dimensional visualization of molecular electrostatic potential surfaces, has had some success in explaining the results of the nitration of substituted imidazo[l,2-fl]pyridines <85EJM50l>. 

After an alignment of a set of molecules known to bind to the same receptor, a comparative molecular field analysis (CoMFA) allows determination and visualization of molecular interaction regions involved in ligand-receptor...
