Course pre-requisite: CHEM 5560 (inorganic proficiency)

Course resources: No textbook is required for this class. Instead, the following resources will be used:

• Class handouts from the chemical literature and from miscellaneous textbooks. Some small handouts will be distributed as hard copies in class, others will be placed on reserve in the science library with a 2-hour checkout, many that are available electronically will be uploaded as pdf files on the class web page or will be e-mailed to the students, and sometimes you will be just given the citation and you have to obtain the articles from the literature yourself.
• Course web page: Click on the course link in http://www.chem.unt.edu/faculty/omary.htm
• Drago, R. "Physical Methods for Chemists", 2nd Edition; OR "Physical Methods in Chemistry", 1^st Edition. Only the 1st Edition is available in the library and will be placed on reserve in the science library.
• Ebsworth, E. A. V.; Rankin, D. W. H.; Cradock, S. "Structural Methods in Inorganic Chemistry", 2nd Edition; CRC Press: Boca Raton, 1991. ISBN: 0-8493-7732-3. This book will be placed on reserve in the science library.

General description of the course:

• The course will introduce the basic principles, chemical applications, and technological applications of a large number of physical and structural methods and techniques that both experimental and computational chemists use.
• The course can be considered either as Special Topics OR Tools Subject for chemistry graduate students.
• THE COURSE IS SUITABLE FOR ALL CHEMISTS, not just inorganic chemists. Students from every division in the department usually take the course and benefit from it for their own research in addition to the general knowledge.
• Inorganic Ph.D. students are particularly encouraged to take the course, in part because taking the course should help them pass the CHEM6010 examinations.
• The course approach will be a compromise between depth and breadth so that one will know more than just “a little bit about everything”. Therefore, methods that are usually suitable for this course but are covered in other graduate courses in the department will not be covered in detail. The first few lectures, however, will introduce most physical methods used by chemists so that the students will learn at least the major principles and applications of the methods that will not be discussed in detail.
• Learning how to combine multiple methods in advanced chemistry research is a central goal for the course. Extensive examples from the literature will be used in class to illustrate how this integration leads to solving important research problems and then each student will be assigned a term paper to do the same.
• Requirements for the term paper:
• Should be written in an ACS journal publication style (the one followed in J. Am. Chem. Soc.). It should be at least 10 double-spaced pages, including figures and illustrations, using the ACS Article Template (which can be downloaded from pubs.acs.org).
• Should be fully documented with relevant references from the original literature (reference to web cites/URLs should be avoided).
• Should have a meaningful integration of at least 3 physical methods that are used significantly to solve the research problem in question.
• The students are strongly encouraged to coordinate with their research supervisors for the selection of the term paper topic. Ultimately, the decision on the term paper topic will be made upon consultation between the student and the instructor.
• Students are encouraged to start working on the term paper early in the semester and are encouraged to consult with the instructor throughout the semester while working on the various phases of the term paper. Every student will be in a position to start working on the term paper since the second week of classes (after the first topic below is finished).

Disability accommodations: All reasonable accommodation will be made to facilitate special needs. However, it is the student's responsibility to make any special needs known to the instructor. It is recommended that students with special needs first meet with the staff of the Office of Disability Accommodation (ODA), Union 324, 565-4323, then meet with the instructor.
