2024-2025 Catalog

Chemistry

Overview

The curriculum of the Chemistry Department is designed to provide the student with a deep and comprehensive understanding of the principles of chemistry, including the laboratory experience necessary for basic research, teaching, and industrial research and development. Each student is expected to carry out laboratory research, working side-by-side with a faculty member on a novel problem at the vanguard of the chemical sciences. Research facilities and instrumentation are excellent and qualified students may begin research as early as their first year. Faculty research grants augmented with support from major corporations and foundations have enabled the department to offer research stipends to qualified students each summer.

To the student preparing for medicine or related professions, training is offered in the fundamental and applied branches of chemistry. In addition, chemistry offers to the liberal arts student an appreciation and understanding of the discoveries, methods, and place of this subject in our society.

The program for majors also prepares students for entrance into the School of Engineering at Columbia University and the Applied Chemistry Program of the California Institute of Technology under the Combined Plan Program. Students interested in engineering should consult the Combined Plan Program for details.

American Chemical Society Accreditation

Discover the excellence of our chemistry programs at Occidental College, where we are proud to hold accreditation from the American Chemical Society (ACS). Our commitment to maintaining the highest standards in chemical education is reflected in our rigorous curriculum. With the ACS approval program, we ensure that our students receive an education of the utmost quality, empowering them to excel in the dynamic and ever-evolving field of chemistry. In order to earn ACS accreditation upon graduation, students are required to complete the essential courses for their Major along with an additional BioChem Class (Chem 350).

Students should familiarize themselves with the departmental requirement at the time of declaring the major. See the Writing Program and consult the department chair for additional information.

Comprehensive Requirement

The student will satisfactorily present a seminar during the senior year on an area of current research in the field of chemistry to an audience of Occidental students, faculty, and guests. The student will also take a comprehensive examination in Chemistry. A student with an overall grade point average of 3.25 can earn distinction with a 75th percentile rank on the examination.

Transfer Credit Policies

The Chemistry Department policy on transfer credit conforms to College policy. AP, IB or A-level examinations in chemistry will not substitute for an Occidental course, place students into advanced courses, or allow a wider opportunity for choice of electives in the department. Students with a score of 4 or 5 on the AP Chemistry examination, or with a score of 6 or 7 on the IB Chemistry examination should enroll in CHEM 130. Students should reference the Transfer Credit section for more details.

Information that can be included in this section include:
  • specific policies for majors/minors
  • AP/IB Exam credit - course equivalencies?
  • Online courses
  • Policies specifically for matriculating frosh, transfer students, returning students after a leave of absence

Advising Information

First-year students interested in chemistry are encouraged to enroll in one chemistry course (see Placement Information below) and one additional lab-based science or math course during their first semester. Students are encouraged to complete their calculus requirements as early as possible. Chemistry faculty are eager to discuss class schedules and other opportunities with students at any time.

Placement Information

Most students who are interested in majoring in Chemistry should take the Chemistry Placement Exam during the summer prior to their first year. Students scoring a 4 or 5 on the Chemistry AP exam have the option of enrolling in CHEM 130 without taking the placement test, but are encouraged to contact the department chair if they have questions about this placement.

Most students who are interested in majoring in Chemistry should also take the Calculus Placement Assessment (ALEKS) during the summer prior to their first year. You do not need to take the Calculus Placement Assessment if any of the following are true:

  • You received a score of 4 or 5 on either the AP Calculus AB or BC exam; 
  • You received an IB Calculus HL score of 5 or above;
  • You have already taken a Calculus 1 course at another accredited college or university. 

An AP Calculus AB score of 4 or 5, or an IB Calculus HL score of 5 or above, fulfills the major’s Calculus 1 requirement. An AP Calculus BC score of 4 or 5 fulfills the Calculus 2 requirement. Students should make sure that their official score reports are sent to the Registrar’s Office for processing.

Chemistry Transfer Student Advice

Transfer Course Limit for Transfer Students: No Limit

Designated Transfer Adviser


Expected preparation for transfer students wanting to major in Chemistry:

  • Junior transfer students

    • Should have completed the equivalent of Occidental’s CHEM 120, CHEM 240, CHEM 220, CHEM 221, and Calculus 2 prior to transferring. If starting in the spring, a junior transfer student should also have completed the one year Physics sequence prior to transferring.

    • Should have completed at least three of the Culture, Fine Arts and Language Core requirements before transferring

  • Transfer students starting mid way through their sophomore year:

    • Should have completed the equivalent of Occidental’s CHEM 120, ideally Calculus 2, and either CHEM 240 or CHEM 220 prior to transferring.

    • Should have completed at least one Core requirement in Culture/Art/Language

  • Sophomore transfer students

    • Should have completed CHEM 120 and ideally Calculus 2 prior to transferring.


General advice for transfer students wanting to major in Chemistry:

  • No online Chemistry Lab courses will transfer into Occidental and count toward the major

  • The Senior Seminar is the only course that must be taken at Occidental


What courses should a transfer student take during their first semester at Occidental?

  • Junior transfer students must take CHEM 300 in their first semester.

  • Transfer students starting mid way through their sophomore year must take CHEM 240 or CHEM 221, and, if they have not already completed it, Calculus 2.

  • Sophomore students must take CHEM 220, CHEM 240, or CHEM 221. Sophomore students starting in the spring semester are advised to take Calculus 2 in addition if they have not already completed it.
