Trippy,

Thank you for that. I had read through the wiki article already but I will look at the referenced links. I recall going over this in instrumental analysis class but since I don't work much with radicals I don't use EPR on a regular basis.

Hi there.

I'm only an undergraduate so I may not be of much help to you, but I recently had a few lecture series on the subject, including bio- applications.

If you're looking to get acquainted with the very basics of EPR, I believe the book Inorganic Spectroscopic Methods by Alan Brisdon (really nice guy actually) has a chapter on it but I'm not completely sure. It's part of a series of short primers published by OUP for undergraduates. If nothing else, its further reading section may be of use.

With regard to biological systems, I've only looked at it in the context of metalloenzymes (deducing oxidation states and the role of non-innocent ligands, in particular). A couple of books I had out for this area discussed (admittedly briefly) how EPR and other methods were used in understanding these enzymes. Principles of bioinorganic chemistry by Lippard and Berg, and Concepts and models in bioinorganic chemistry edited by HB Kraatz, were both quite useful.

Sorry if these aren't advanced enough for you, but I hope they're of some use. The latter two have some fascinating material in them in any case.

Kaeroll,

Thank you for the recommendation. I will see if our library carries this. I think I am getting a handle on this. Well as much as you can from reading textbooks.

Caleb

As I am an undergraduate as well with limited experience in this area of electron spin resonance. When we were discussing this as in terms of of utilizing the technique that is free radicals in biological/chemical systems. We haven't ever done experiments in 'spin trapping' or anything. I guess best bet is to try and review peer data bases, and legitimate online resources. Brush up on as much as you can for your advantage before hitting the lab. Happy trails!

Maybe those links can help you out?

Have you looked at the new superlenses?
" Conventional lenses can only see details roughly down to the size of half the wavelength of light. This limit is due to interference and diffraction that occurs as light bounces off an object. A superlens gets around this limit by collecting light waves that only occur very close to an illuminated object. These "evanescent waves" contain information about at finer resolution but are hard to use because these waves decay rapidly. The nanometre-scale region in which they exist is known as the "near-field".

Here and here.

Thank you for your discussion. The same problem happened to me. It is very helpful to me.
