What the UVM Catalogue says about CHEM 201 - Advanced Chemistry Laboratory: "Laboratory problems requiring modern analytical, physical, and inorganic synthetic techniques." What we think you are saying at this point in your college career: I have finished 2½ years of chemistry. I have completed organic chemistry, and organic lab was awesome. How do I get exciting labs in other areas of chemistry? I mean, freshman chemistry was ok, but doing labs like titrations with a burette and dye indicator are boring and tedious. I would like to use modern instruments, but adding a pH meter to the titration is not my idea of modern. I want to perform experiments that really use sophisticated instrumentation and challenge my thinking.Yes boys and girls, that is what we hope we have for you in this two course sequence, Chem 201 & 202. CHEM 201 is also a spectroscopy course where you get to learn all about and use:

|
Prerequisites that are important: |
|
Lecture: |
Mon., Wed., & Fri., 1:55-2:45 pm, Angell B203 The foci of Advanced Chem Lab are the laboratory experiments and the lab write-ups and presentation. The purpose of the class time is to provide lectures about the chemistry and instrumentation that will be in each laboratory. As such, we won't need to meet for 3 class days a week. See calendar of classes for which days class will meet. |
Laboratory: |
Tues., 1:00-7:00pm, Cook A105 & the 2nd floor NMR/GCMS room |
Text: |
No text covers the diverse laboratories in the course. Readings will be provided as (i) xerox copies of articles from the scientific literature, (ii) chapters from books and (iii) books on reserve in the chemistry library. Students will also have to search the literature for additional articles and book chapters relevant to particular laboratories. |

UVM Policy on Absences: |
Religious Holidays: Students have the right to practice the religion of their choice. Students should submit in writing by the end of the 2nd full week of classes their documented religious holiday schedule for the semester if there are any conflicts with the class or laboratory schedule. Inter-collegiate Athletics: Members of UVM varsity and junior varsity teams are responsible for documenting in writing any conflicts between their planned athletic schedule and the class (& laboratory) schedule by the end of the 2nd full week of classes. |
UVM Policy on Academic Integrity: |
Offenses against the Code of Academic Integrity are deemed serious and insult the integrity of the entire academic community. Any suspected violations of the code are taken very seriously and will be forwarded to the Center for Student Ethics & Standards for further investigation. |
How the course grade is determined: |
|||
| Points | |||
| Written lab reports (5 x50 points ech - see link on lab reports) | 250 | 72% | |
| Oral lab report (1) | 50 | 14% | |
| Lab performance and lab notebook | 30 | ||
| Participation during oral presentations | 20 | 50 | 14% |
| Total: | 350 | 100% | |
| Update the literature used for the various labs. Bring me (DEM) a good article from the literature or chapter from a book reviewing or discussing a key aspect of any of the labs that is newer and better than the existing references already cited for the lab, and I will give you 5 points up to a maximum of 30 points. | |||

Synopsis: |
#1:
|
1 lab day. You will learn how to use a high resolution Fourier transform-infrared spectrometer (FT-IR). We will take advantage of the FT-IR's high spectral resolution to measure various physical chemical vibrational properties of diatomic gases. The 1st gas to be studied will be CO at normal and high resolution modes. The 2nd gas will be HCl. Here you will be able to distinguish the isotopes of 35Cl and 37Cl. You will also prepare 2HCl and measure the spectrum of 2HCl. You will calculate the physical chemistry rotational and rotational-vibrational parameters for both 1HCl and 2HCl. You will also calculate bond strengths from the measured mechanic parameters of these oscillators. |
#2:
|
1 lab day. You will learn to use the Bruker 500 MHz NMR. We will take advantage of the instrument's resolution and sensitivity to acquire 1H data for the keto-enol tautomerization equilibrium of ethyl acetoacetate and acetylacetone and measure the equilibrium constants in two different solvents. |
#3:
|
1 lab day. You will use our research-grade UV-visible spectrophotometer and our fluorometer to investigate the fluorescence emission spectra of polyaromatic hydrocarbons (PAHs). The vibronic features of the fluorescence will be related to conventional IR absorptions. By measuring the fluorescence over a range of concentrations of PAHs, the excimer formation will be determined and translated into thermodynamic parameters. |
#4:
|
1 lab day. You will learn how to manipulate, move, sample and measure gases using a vacuum line. Two gases, BF3 and (CH3)3N will be combined to form a solid-state product. The product will be characterized to confirm the reaction. |
#5:
|
2 lab days. You will learn to use the flame spectrophotometer to measure calcium & sodium ions in solution. This experiment has two parts, one dealing with metal ions measurement by flame emission and the other calcium ion measurement by atomic absorption. This lab will focus on methods of quantitation and interferences. Samples will be checked for their metal ion and calcium content. |
#6:
|
2 lab days. You will learn modern separation techniques via gas chromatography (GC) and analysis techniques via mass spectrometry (MS). You will use the Varian Saturn 2100T ion trap GCMS to make your the measurements. You will also learn chemistry required to prepare biological samples for GC measurement by performing micro-chemistry reactions on samples of amino acids. You will separate the individual amino acids by GC and collect spectra by MS for identification of each compound. Using standard mass spectra analysis techniques, you will confirm the identity of each amino acid peak. |
