Classes

  • 25 classes are planned for Fall 2018. M and T classes (‘MT’ in the schedule) cover the same material, as do W/Th classes (‘WR’ in the schedule).
  • Labor Day: no lectures MT 9/3-4, no lab lecture M 9/3. Labs meet 9/4-7.
  • Fall Break: no classes or labs M-F 10/15-19
  • Thanksgiving: no lectures WR 11/21-22
  • If you miss your lecture, you may attend the other session. Notify the instructor.
  • If you miss your quiz day, notify the instructor immediately. You may not attend the other section without prior consultation with instructor.
  • 201 covers Sorrell (textbook) Ch. 1-14 plus some material not found in the textbook. Ch. 1-13 are covered in class according to the schedule listed below, roughly one chapter (2 lectures) per week. Ch. 14 and material from outside the textbook (the latter includes molecular and electronic structure models, and so-called ‘nonbonded’ interactions between atoms) will be covered during lab periods and lab lectures. Lecture-only students should plan to attend relevant lab sessions to learn this additional material (consult the instructor for the schedule).
  • Five quizzes will be given during scheduled classes. Each quiz will last somewhere between 20-35 minutes and will be given at the start of class. The remainder of the class period will be used to cover new material. See Exams for more info.
