Really interesting tool that turns text into spam and back into text again. It took: An interactive site for hard science learning aids, links, and class notes ... and turned it into: Dear E-Commerce professional ; This letter was specially selected to be sent to you . This is a one time mailing...
All COSIC publications from 1981 until now, organized by date. There is also a handy search page. COSIC research goal "is to create a secure electronic equivalent for interactions in the physical world such as confidentiality, signatures, identification, anonymity, payment and elections." COSIC is...
This video show how a series of sp2 hybridized atoms can form multiple double bonds that are in resonance.... It's a lot of information packed in a 30 second clip all about benzene.
This video was produced to help students of human anatomy at Modesto Junior College study our anatomical models....
This is a real good intro to 1H NMR by a professor from Rochester Institute of Technology. It might be a little long for a review but definitely in enough information to get you started in the wonders of NMR.
This is a quick review on fructose. It goes over concepts such as the anomeric carbon, the different isomers and the ring structure. This is great for a last minute review.
In these two paragraphs CW-NMR is explained. Even though the instrument is generally not used any more it gives you an idea of where modern day FT-NMR's come from.
I realize this might be better suited for the Math section but since pascal's triangle has a micro-implementation in NMR spectroscopy I thought it might be somewhat interesting. There is a lot of information on this site about pascal's triangle.
This short review is more geared towards protein crystal growers. There is a very basic intro to crystallography and then some info on how to grow crystals. It is well written and easy to understand.
This is a nicely done short description on Bragg's law and its use in determining atomic structure of crystals. There is a well done applet and some good examples of experimental diffraction patterns to help with the understanding of Bragg's law.
These are the slides about molecular orbital theory. I would use this as a quick review before an exam. There are some really good practical examples and explanations.
LCAO is an easy quantum mechanical method which helps determine the true wave function of a molecular orbital. This site gives an in depth explanation of the math behind LCAO and some pretty good examples.
A nice little review about point groups and molecular symmetry. Not only does it give the theory but also nice jmol examples. Probably not as detailed as a beginner to point groups would like but enough detail for a quick review before an exam.
This reaction is one of the biggest discoveries in modern chemistry. "The Suzuki reaction is the organic reaction of an aryl- or vinyl-boronic acid with an aryl- or vinyl-halide catalyzed by a palladium(0) complex.[1][2] It is widely used to synthesize poly-olefins, styrenes, and...
Text based description of reactions with alkanes, alkenes and alkynes. This is a straight forward review with specific examples.
A purely text base tutorial on alkanes. It is well written and pretty basic stuff, but a good overview non the less. "Open-chain alkanes (without rings) all have the general formula CnH2n + 2, where n equals the number of carbon atoms. The following table shows the...
An explanation about organic acids and bases with a little bit of a different approach. There are some really easy to grasp rules that will help you determine strength's of organic acids and bases. One example is "Anything with a hydrogen bound to an electronegative...
This site thoroughly explains bases from an organic chemists' point of view. There are some intermediate examples such as phenylamine and how the aromaticity of the phenyl group affects the amine.
This is a pretty thorough explanation of organic acids. From my experience most organic reactions can be explained through acid-base chemistry, if one has a thorough understanding of organic acids and bases.
Just a quick refresher on the four laws of thermodynamics. Usually lower level chemistry courses require you to only know about I, II and III. "The four principles, or laws, of thermodynamics are:[1][2][3][4][5][6] The zeroth law of thermodynamics allows the assignment...
