Introduction
    There are many ways to characterize a reaction product.  It may be as simple as taking a melting point or as complex as doing Mossbauer Spectroscopy.  Common characterization techniques in Inorganic Chemistry include infra-red (IR), electronic (UV-visible) and nuclear magnetic resonance (NMR) spectroscopy.  In this lab, we will begin a preliminary examination of these methods of sample identification.
    With any research project, it is important that library searches are used to determine previous work in the area of interest and to help identify new compounds by observing the results of similar measurements on similar compounds.  Fortunately for the current class of chemistry majors, many of these results have already been tabulated.
     For this lab assignment, you will become familiar with the A.S.U. library, you will find important information related to IR and NMR peak assignments and you will search the internet for information concerning IR, UV/visible, and NMR spectroscopy.

Library Assignment
    It is important to know your way around the library.  In this portion of the assignment, you are to find the location of the following:
 a)  main desk
 b)  chemistry reference material
 c)  Chemical Abstracts
 d)  current journals (unbound)
 e)  bound chemistry journals
 f)  chemistry related books
 g)  Science Citations
 h)  inter-library loan

    Be sure to include exactly where each of these sections are located, not just the floor.  If it is on the north side of the 4th floor, a quarter of the way from the east wall, tell me.  You may want to include a map.  For your reference, Wilson and the Administration buildings are north of the library.

IR and NMR correlation tables
     The identification of a product by either of these techniques depends on the position of the peaks in the spectrum.  The peak position depends on the functional group (IR) or the chemical environment of the observed nuclei (NMR).  You are to find and summarize in a table (DO NOT PHOTOCOPY) the characteristic infrared absorption frequencies for a) typical organic groups and b) typical inorganic groups, and proton NMR chemical shift values for typical organic protons. (List a minimum of 10 groups/ a maximum of 20 groups for each table).
     Once the correlation tables have been completed, you are to copy an IR spectrum of an organic compound from the Sadtler index and assign the peaks.  The compound must have at least one functional group.  On the same compound, find the NMR spectrum and assign the peaks based on the chemical shift table prepared from above.

Internet Search
    Using one of the search engines from experiment 1, search the internet for companies which deal with IR, NMR and visible spectroscopy.  Record names and websites for all companies in each of the three categories (up to 10 maximum).

Write-up
    The report must follow the guidelines on the Lab Report page.  The minimum report should include the results of your library searches (locations), IR and NMR correlation tables and spectra, a brief description of the spectra and a summary of the internet results. The report will be due by 5:00 pm on Friday, Feb. 15, 2008.  This lab will be worth 30 points of your lab grade.  No late reports will be accepted.  Note: do not wait until the day before the lab report is due to start the experiment.
