Molecules Definition and 561 Threads

In 1999, Zeilinger and his colleagues fired beams of "carbon-60" or "carbon-70" molecules (so named because each molecule contains 60 or 70 carbon atoms) at a device called a diffraction grating. The individual molecules spread out in wavelike patterns, creating "interference patterns" visible...

Which are good databases to find 2D structures of molecules like the following: http://www.accelrys.com/cases/images/melanin2.jpg It is supposed to be a form of melanin, but I need a better one :) Swissprot won't work, since it is not a protein.. couldn't find anything in Entrez either :(

Are metal "molecules" actually molecules? As the title asks. Are things like FeC actually molecules? The way I read the defintions, a compound is a molecule consisting of more than one element. Metals are capable of more than one type of bonding. We can reduce any metal to a small group of...

http://www.newscientist.com/news/news.jsp?id=ns99994552 Maybe is true after all that we are all "sons of the stars" This is a strong evidence that life is spread throughout the cosmos, don't you think?

I had never really heard anything about this, and now that I am reading about it, I am finding the results convincing. (Although I am still only just starting to get my hands on the actual results themselves, so I can't be certain yet). I am talking about work done on measuring the frequency...

What types of simple geometric shapes are represented by molecules? I think of linear polymers, DNA, buckyballs, benzene rings, various crystal lattices... What comes to your mind? Other polygons, hyperbolas, parabolas, spirals, fractals, ovals...? How about what's the most random or...

Can scientists see either atoms or molecules? If not, what is the smallest object/entity we can see?

I have read about experiments where entire atoms and even whole molecules were held in a state of quantum superposition. It wasn't until an observation was made that these molecules left their indeterminate state. If whole atoms and molecules can exist in quantum superposition, does theory...

I'm interested in engeeniring molecule with specific max. e-m wave apsorption. How to, where from to start ? eg. Like one used for blocking UV rays (btw do you have formulas of these molecules).

Which is the known molecule that is composed by the major number of atoms? DNA? I know that DNA is made of million of atoms

Water is a dipole right? Having a slightly positive side and a negative side. If this is true, then won't water molecules have a certain arrangement or pattern? Due to the "poles" attracting and repelling? Just like how magnets, which when stuck on sticks in a grid format, will...
