You can easily and pretty accurately estimate the solvation entropy using ChemSol: http://futura.usc.edu/programs/index.html For the configurational entropy, just use restraint release, as outlined in e.g. Strajbl et al., Calculations of activation entropies of chemical reactions in solution, J. Phys. Chem. B. 104 (2000), 4578 This will give you the total entropy quite accurately. Good luck!

This workshop will be held in conjunction with the 4th IEEE International Conference on e-Science (e-Science 2008) in Indianapolis, Indiana, USA, December 7-12 2008. Cheminformatics is becoming an increasingly important part of drug discovery, chemistry, biology, toxicology and environmental science. There are now huge volumes of information about chemical compounds and their related biological properties available in the public domain, as well as in proprietary databases, and a large number of computations that can be applied to this information. There is thus much interest in the application of eScience and cyberinfrastructure to such information mining and computation problems. We are requesting papers that will cover a variery of aspects of this emerging application of eScience and grid computing in chemistry, cheminformatics, biology, toxicology, environmental science and computer-aided drug discovery. Papers should address one or more of the following areas: * Computation on extremely large chemical datasets (>10m chemical structures) * Distributed data mining of large chemical and biological datasets * Grand challenges in cheminformatics * High impact opportunities for cheminformatics and eScience * Cloud computing infrastructure requirements for cheminformatics * Chemistry-aware search engines and journal article processing tools * Natural Language Processing and Semantic Web applications More information can be found on the conference website at http:// cheminfo.informatics.indiana.edu/eScience2008/ .
