Have you StruMM3D a molecule today?

====================

We pronounce StruMM3D like “strumm 3D”, or, better still, “strummed”. Indeed, we use it to reveal, display, and examine, the sweet molecular music that nature plays, and the currently available version is the best ever.

StruMM3D was used recently to uncover new information about the ferrocenes and ferricenium ions.

Recently StruMM3D has been rated as - “Awesome, easily the best molecule viewer/modeler of all time. The information StruMM3D mines from diffraction (XYZ) data, and molecular models, is most impressive.”

====================

The rational starting point in the molecular modeling of any organic molecule ought be the process of ascertaining how well the known (experimentally determined) properties of that molecule (physical and chemical) can be simulated by considering, initially, only its the bond length, bond angle, and dipolar features.

It is only if this initial simulation of the dipolar features of any molecule proves to be inadequate, that one can truly begin to understand the contributions that are being made to the molecule’s structure, and properties, by delocalization and quantum mechanical (QM) effects.

This notion is especially important since it is well known that QM programs cannot reliably simulate lone pair repulsions, and offer poor simulations of dipolar effects in general, unless another multitude of assumptions are made. Hence, dipolar simulations are best done with molecular mechanics (MM) programs.

Your molecular modeling program MUST allow you to examine all of the molecule's potential energy data. Indeed, these data, for each, and every bond, bond angle, and lone pair interaction, can give invaluable insight into the most subtle and important features of the molecule. Only after examining all this data will you truly UNDERSTAND the real roles of these dipolar data, Most QM programs, and many MM programs, CANNOT give you this data, and so you will have NO idea how the modeler arrived at it's molecular energy distribution.

StruMM3D does give access to all the molecular dipolar and other strain data, routinely, without special effort.

Regardless of the hype that is bandied about by users of QM programs, most of whom know little about the design and assumptions embedded in these programs, the reality is that QM calculations are far from being “ab initio”. It is impossible to generate an exact solution to the wave equation of the helium atom, and any solution requires a host of approximations. Imagine, then, the multitude of approximations needed for the “ab initio” solution of the wave equation for the simple, small, molecule methanol.

Is it surprising that most QM investigations begin with MM generated molecular models?

====================

One thing became painfully obvious during our testing of StruMM3D in Windows 7/8, the UAC feature of Windows 7/8 is of questionable utility, and might simply be ill-intentioned.

So why does Microsoft use the UAC feature to try to frighten users away from programs they did not develop, and now designate as from an “Unknown Publisher”? Is the user only supposed to use programs published by Microsoft? And then, even some Microsoft programs generate the "Unknown Publisher" annoyance. The only people that benefit from the Windows 7/8 UAC are Microsoft, and its satellite companies that try to milk small software developers in order to digitally sign their software. The UAC is a Microsoft scheme to crush private software developers. So, just re-assert your independence from these monopolists and turn off the UAC feature. There are excellent anti-virus and anti-malware programs around, especially within the Windows 7/8 OSes, and so the chances of a careful user unintentionally executing malware are miniscule in today's computing environment, , unless you habitually ignore your computer's anti-virus and anti-malware programs warnings.

====================

Update Your StruMM3D program

StruMM3D tells you when a newer version is available so that you can get it. However, if you haven't updated your StruMM3D recently, go download and try the newest version of StruMM3D. It will be faster and just awesome! Remember to visit the StruMM3D FAQ for hints, user/program tips and additional help.

Users of versions of Str3Di32 must update to StruMM3D, which has total backward compatibility with all Str3Di structure files. Current users of StruMM3D should download only StruMM3D.ZIP and unzip it into their Str3Di folder/directory, to apply all recent updates.

====================

If you're not using StruMM3D, then why not?

If you regularly review structures that have been determined by the diffraction methods (x-ray crystallography etc.), then you simply MUST use StruMM3D to visualize your data. StruMM3D is the ONLY molecular modeler that enables you to spot (visually) weird bond lengths, among other oddities that find their way into diffraction studies. Serious crystallographers always use StruMM3D.

Do you want to see how good your current molecular modeling program is? Or isn’t. Then we dare users of other molecular modelers to see how quickly they can complete one of our very routinely done molecular modeling tasks. This one involves using your current molecular modeling program to spot flaws in the coordinate data of published x-ray crystallographic investigations. Try it.
