Objectives and Procedures (adapted from the course notes of Prof. Lloyd Dolby who developed this course over a 30 year period here at the U of O): The first objective is not to get hurt. Everything else is a bonus. The course is designed to be an introduction to laboratory research with attendant frustration, bewilderment and joy. The work of the course is identifying nine organic compounds (including six single unknowns and 3 compounds in a mixture). The first two unknowns are to be identified without spectroscopy. IR may be used after the first two compounds. NMR spectra will be provided after the first three compounds (C through the mixture) up to a total of nine spectra. Stockroom personnel will prepare NMR samples of the single unknowns and the spectra should be available when the compound is obtained or shortly thereafter. Students are responsible for making up NMR samples of the components of their mixture. Students will measure their own infrared spectra after completing the first two unknowns. One mass spectrum and one 13C NMR spectrum will be provided for each student.

The amounts of compound distributed are more than adequate for identification and derivatization of your unknown. There is a 50 point penalty for additional quantities of an unknown.

Unknowns are to be reported on the form provided. Another unknown may be obtained as soon as one has been completed and the report submitted. Students will always have two unknowns to work on. You are welcome to discuss your work with the instructors and obtain help planning experiments provided that you have your lab notebook with you.

In the interest of fairness, no lab work is permitted outside of the teaching laboratory. No spectra for this course are to be measured on research instrumentation. No samples are to be removed from the laboratory. Violations will be treated as cheating.

Professor DolbyÕs rule of thumb in this course and in research is that two weeks in the laboratory will save you an hour in the library every time.

Safety: See the safety handout for details. You are responsible for following the rules and guidelines explained in the safety handout. Any student whose deliberate or negligent acts endanger his/her own safety or that of others may be expelled from the laboratory.

Notebook: A bound notebook with consecutively numbered pages must be used. All written work connected with the lab is to be recorded in permanent ink. It is important that you record all of your data in this notebook.

Attendance: Lecture attendance is required. Important announcements will frequently be made during lectures. No one will be permitted to work in the laboratory except those people scheduled for that section or those with prior permission from instructors. If you have a valid excuse you may be able to make-up a lab, but only if there is space available in a lab section. The capacity of the labs will not be exceeded to accommodate make-up labs. No make-up lab sections will be added.

Computer Access: Each student should have an account on Gladstone or any server that will allow access to e-mail, newsgroups, and the World Wide Web. The science library staff will help you set up an account on Gladstone : see the staff person at the X-terminals between 1 p.m. and 5 p.m. during the week to set up an account.

E-mail: Please learn how to send and read e-mail messages. You can contact instructors and TAs via e-mail.

Virtual Office Hours: There is a listserve (ch339) for the course. The purpose of this listserve is to establish Òvirtual office hoursÓ for the course to augment the normal office hours of the instructors and TAs. Students may post questions to the list or make suggestions regarding questions posted by other students. The list will be monitored by the instructors and TAs to help answer questions and to make sure that the information being exchanged is accurate. If you know the answer to another studentÕs question, or have a suggestion about where they can find the answer to their question, please contribute to the discussion (after all, that is the purpose of this list).

WWW (world wide web): There is a home page for the class. To access the home page use the URL:

Here you will find electronic versions of handouts and other course materials. Check it out.

Grading:

Unknowns (based on total of 100 pts./unknown: 50 points for correct identification, 25 points for preparation of a satisfactory solid derivative, and 25 points for the write up)......45 %

Evaluation and notebook......20 %

Midterm.....15 %

Final....20 %

An A grade can be earned without taking the final exam if all of the unknowns are correctly identified (a satisfactory derivative and a complete report are required) . Students who must take the final can also obtain an A.

Exams: There will be two exams given during the course:

Midterm: In class, Wednesday, April 30.

Final: 3:15 p.m., Monday, June 9.

Missed exams will count as zeroes in your final grade; there will be no make-up exams and no exams will be given early. If you have an acceptable reason for missing the exam, your final grade will be based on your other point totals throughout the course.

Check-in: Lab check-in and lab work starts the first week of classes. Registered students should check-in and claim their lab locker at the beginning of the class period. Failure to attend the first day of lab will result in the forfeiture of your assigned spot and you will be placed on the waiting list.

Check-out: The security of your locker is your responsibility. You will be charged for broken or missing items; your desk must be fully stocked upon check-out. Failure to check-out will result in a $25 fine in addition to any charges for broken or missing items.
