Hours/Credits:          1 hour lecture per week, 5 hours lab per week, 3 cr.

                                    Lecture and lab is given once per week.

                                    This course is counted as a writing course (W) to partially fulfill the elective-level course requirement.

 

Textbook:                  None. Extensive original literature searching and retrieval is necessary for the laboratory reports.

 

Course objectives:

This course follows in a sequence of Physical Chemistry I and II and Physical Chemistry Laboratory I. Chemistry 43400 is a requirement for the chemistry major-standard option. Students will be introduced to advanced instrumentation, such as infrared absorption spectroscopy, Raman spectroscopy, ultraviolet-visible spectroscopy, electrochemistry, time-resolved fluorescence, and X-ray diffraction. The laboratory experiments will be focused on the interpretation of spectra, voltammograms, and diffraction patterns in order to understand electronic and vibrational energy levels within molecules, reduction-oxidation (redox) reactions, and symmetry and structures in solid state crystalline materials, respectively. Students will be able to present their experiments including results and discussion in formal laboratory reports written in the style of professional scientific journals.

After completing this course, students should be able to:                                    Dept outcome letters

    aqueous solutions.                                                                                            a, b, c, d, e, f, i

4. Collect Raman spectra on tetrahedral molecules and ions and compare

    the frequencies of vibrational modes to theoretical models.                  a, c, d, e, f, I

5. Interpret powder X-ray diffraction patterns of crystalline solids and

    compare to known diffraction patterns from the literature.                   a, b, c, d, e, f, i

6. Collect time-resolved fluorescence spectra and calculate lifetimes.       a, c, d, e, f, I

7. Design an experiment related to physical chemistry with attention to

    experimental techniques and instruments and interpretation of data.                a, e, f, i, j

8. Write complete laboratory reports including abstract, introduction,

    experimental methods, results, discussion, and references.                  f, g, i, k

Grading Scheme

6 lab reports: 15 points each.

 

Each lab report will be a group effort. Each student will be assigned a section from the following: abstract, introduction, experimental methods, results, discussion, and references. One student will be the group leader to compile all sections, format, and submit the report on time. Each student will be given questions to answer at the end of the report.

(5 points overall report, 5 points individual section, 5 points individual questions)

 

No late lab reports will be accepted.

 

Lab reports must be in scientific journal article format (abstract, introduction, experimental, results, discussion, conclusion, references, appendix for all data and calculations). Each person will be asked to focus on a different section.

 

1 Presentation with an oral exam (during the last 2 weeks of the semester): 10 points.

Each student will give a PowerPoint presentation on one randomly chose laboratory experiment. The presentation must be 10 minutes in duration followed by student questions and an oral exam by the professor.
