                             and Attendance
                             Exams               300 pts        (40%)

Total points: 750
Letter grades will be assigned as follows: A (675-750), B (600-674), C (525-599), D (450-524), F (449 or below). Keep in mind that +/- grades are included in the ranges shown above.

Assignments: Homework assignments are due at the beginning of class on the dates indicated in the course outline. Late assignments will not be accepted. These problem sets will be graded on a 10 point scale, and grades will be assigned based on completion and overall quality. Be sure to show all work: present your answers as if you are trying to convince me that your structural assignment is correct. Full credit will not be given for answers that show only a structure and no explanation. Answer keys will be posted on the bulletin board outside of my office and will also be on reserve in the library.

Exams and Quizzes: There will be 3 quizzes and 3 midterm exams. Quizzes are intended to encourage you to stay current with the work and to help you identify "trouble spots" before taking the exams. The exams will be administered in lab on September 25, October 23, and November 20. See the course outline for quiz dates.

Lab: The lab grade consists of the total of three lab reports (40 points each) and a grade on lab technique (15 points). Lab technique includes: proper handling of chemicals and equipment, lab hygiene, and group etiquette.

It is imperative that you come to the lab fully prepared. Careful planning and preparation before you arrive at the lab will allow you to complete your experiments in an efficient and safe manner. Missing or arriving late to prelab will result in a reduced grade and/or dismissal from the lab.

Unsafe behavior in the lab will not be tolerated and violations will be penalized. Repeated violations during a class may result in a zero for that lab. Lab safety and policy will be addressed at the first lab meeting.

Attendance is mandatory. Three absences are permitted. Each additional absence will result in a deduction of three points from the participation and attendance grade. Make-ups are not permitted for quizzes or labs unless the absence has received prior approval from me. The final exam grade (%) will be substituted for an exam that is missed due to an excused absence. Remember, I need to be notified prior to the absence. In case of an emergency, you may call me at home or call Theresa's office (4180) and leave a message on her machine. Notification via the Dean's office is also fine.

Participation: The key to success in this course is to work lots of problems. I expect everyone to try the problems given in class. Also, participation in class discussions regarding problem-solving techniques and solutions to problems is encouraged and expected.

Academic Dishonesty, such as copying the work of another or allowing someone else to copy your work and submit it as their own, whether it be on an exam, quiz, lab report, or assignment, will not be tolerated. Penalties for academic dishonesty range from receiving a failing grade on the assignment to dismissal from the college, depending on the nature of the offense. For more information regarding the College policy on academic dishonesty, consult the Pathfinder or Student Handbook.

Extra Credit: Extra credit points (3) can be earned by attending departmental colloquia, up to a maximum of 21 points. Extra credit points will be used to nullify points lost due to unexcused absences before they will be applied to one's grade.

Course Outline

Every effort will be made to stick to the schedule outlined on the next two pages. Keep in mind that it is quite possible that we may get ahead or behind the schedule by a day or two. If you have any questions regarding the schedule, please don't hesitate to ask.

A few notes regarding the schedule:

All exams will be given on Thursdays, during the lab period. These dates will not be changed.
Quiz dates are tentative and may vary depending on our progress with the lecture material. If we need to move a quiz, I will make every effort to give at least a week's notice.
The homework assignments are listed on the day that they are due. You should work on the assignments as we cover the material in class. Although the assignments consist of only a few problems, please realize that some spectral problems may require a considerable amount of analysis (and time). Also, I have found that even simple spectral problems can become incredibly difficult if I have not had enough sleep or can not concentrate well for some reason.

One final note:

Every chemist develops his or her own method for solving problems. This is especially true in spectroscopy. The only way anyone ever becomes proficient at solving spectral problems is by working lots of problems, making the occasional mistake and learning from those mistakes. Try not to get frustrated if the problems seem kind of tough at first--with patience and practice they get a lot easier. Most importantly, try to have fun!! What other class gives you credit for working puzzles?!?!
