It includes the previous version (which covered literature between 1970 and 2002) plus an update containing articles until the end of 2003. The database was compiled by Professor Philip Kocienski (E-mail: P.Kocienski@chemistry.leeds.ac.uk) and Dr. Krzysztof Jarowicki (E-mail: krisj@chemistry.leeds.ac.uk) School of Chemistry, University of Leeds, Leeds LS2 9JT, U.K. http://www.chem.leeds.ac.uk/ The authors do not accept responsibility for the accuracy, content, or selection of the data. Synthesis Reviews is sponsored by Georg Thieme Verlag and is provided as a service to the synthetic community. Synthesis Reviews (covering the literature from 1970-1994) and the first supplement (covering the literature for the year 1995) was originally provided free on disks to all subscribers of SYNTHESIS published by Georg Thieme Verlag. Synthesis Reviews is not copy-protected and copies can be freely circulated. The version provided here combines the original database and supplements together with corrections. There will be semi-annual updates. Release dates of the updates will be announced on the SYNTHESIS website.

Graduate Tuition Waived Contact Dr. Jordan Poler for details NEW! Gary Howard Research Fellowship NEW! Everett Foundation Fellowship Master's Degree Program: The Department of Chemistry offers a research based Master of Science (M.S.) degree. This master's degree requires successful completion of two advanced graduate chemistry courses, regular participation in Chemistry Department seminar programs, and a research thesis based on original research carried out under the direction of a member of the graduate faculty. Students choose a research advisor during their first semester in the Master's program and are encouraged to begin hands-on laboratory work as early as possible. Graduate students select a research thesis committee for additional guidance and have several opportunities to display their research progress to their M.S. committee members and peers. Overview: Regional Analytical Chemistry Laboratory (RACheL) . A Master of Science in chemistry is an excellent terminal degree in preparation for careers in chemical research, pharmaceutical chemistry, textile chemistry, food chemistry, and power industries. A master's degree (M.S) in chemistry may also serve as a useful step toward professions such as medicine, pharmacy, industrial hygiene, and patent law, and toward further study in chemistry, physics, biology, and other scientific and engineering disciplines. Graduate students from this program thrive in a variety of career paths.

Infrared Spectroscopy Introduction Infrared Spectroscopy IR of Organic Compounds IR of Inorganic Compounds ... Sample Preparation Introduction When a beam of electromagnetic radiation of intensity I o is passed through a substance, it can either be absorbed or transmitted, depending upon its frequency, , and the structure of the molecule it encounters. Electromagnetic radiation is energy and hence when a molecule absorbs radiation it gains energy as it undergoes a quantum transition from one energy state (E initial ) to another (E final ). The frequency of the absorbed radiation is related to the energy of the transition by Planck's law: E final - E initial = E = h n = hc/ l . Thus, if a transition exists which is related to the frequency of the incident radiation by Planck's constant, then the radiation can be absorbed. Conversely, if the frequency does not satisfy the Planck expression, then the radiation will be transmitted. A plot of the frequency of the incident radiation vs. some measure of the percent radiation absorbed by the sample is the absorption spectrum of the compound. The type of absorption spectroscopy depends upon the type of transition involved and accordingly the frequency range of the electromagnetic radiation absorbed. If absorption is accompanied by a transition from one rotational energy level to another then the radiation is from the microwave portion of the electromagnetic spectrum and the technique is microwave spectroscopy. If the transition is from one vibrational energy level to another, then the radiation is from the infrared portion of the electromagnetic spectrum and the technique is known as infrared spectroscopy. If the transition alters the configuration of the valence electrons in the molecule, then the radiation is from the ultraviolet-visible portion of the spectrum and the technique is ultraviolet-visible, or electronic absorption, spectroscopy.
