Chem 6 ab Application of Physical Methods to Chemical Problems

List of Experiments

The course consists of ten units, six being spent in the lab and four being spent analyzing data outside the lab.  There are currently 10 possible experiments available for this course, although some of them may be not offered each term. Four experiments will be performed each of two quarters (winter and spring) by each group of two students.  Thus, each student will complete four experiments per term.  A two-week period will be allowed for the completion of each experiment.  Some experiments are installed in the room 33 Noyes, which is specifically designated for this laboratory course, while some others are part of research facilities in the Beckman Institute or Crellin.
