This is a computational/molecular modeling supplement to the synthesis of [1,3,5-C6H3(CH3)3]MoCO3 included in the third edition of "Synthesis and Technique in Inorganic Chemistry" (see full citation below)*. Students optimize the model and compute an infrared spectrum and compare it to their experimental (solution) spectrum.

Computational software package such as the Gaussian.
Software training was minimal--an hour was devoted to using the GUI interface to Gaussian 03--and was accomplished during the first lab session. The majority of questions,which were generally software specific questions,were fielded as students did their modeling. Since this is computer based work, ready access to modeling software during laboratory sessions is required. My students do their experiments in a round-robin format, thus the number of computers needed during any single lab session is minimal (1-3), though for the initial training I did make use of a computer lab.Input of the model takes at most an hour,less if the students are reasonably familiar with the computational software,so students should be able to perform other work during a typical 3 hour lab session.
