St. Olaf traditionally graduates more chemistry majors than any other four-year college in the United States. The college also ranks in the top five as a source of students who obtain the Ph.D. in chemistry and related fields. Chemistry faculty members have a fine record of achievement in teaching and research; several have won prestigious national awards. Students enjoy state-of-the-art instrumentation and computers in both laboratory and classroom.

The Chemistry Department offers an array of courses in the traditional areas of chemistry (organic, analytical, physical, inorganic). Courses in biochemistry, organometallic chemistry, environmental chemistry, and other topics introduce students to interdisciplinary and bridging sciences that utilize a chemical perspective.

The department has an active summer research program, in which faculty and students work together to investigate problems of current interest. Students graduating with chemistry majors have had excellent success in gaining admission to graduate and professional schools and in obtaining employment opportunities. A major in chemistry may lead to employment in chemical research and in related areas such as medical applications of chemistry, environmental chemistry, and materials science. A chemistry major also provides an excellent background for continued education in professional schools in medicine, dentistry, pharmacy, and related fields.

Requirements for a Graduation Major

Majors must complete Chemistry 125 (or 121 and 123), 126, 247, 248, 255, 371, laboratory courses 253, 254, 256, 357, and one additional course from 252, 260, 379, 380, 382, 384, 386, 388, or 391. The Chemistry/Biology integrated course sequence (Chemistry/Biology 125,126 and 127) may be substituted for Chemistry 125 and Chemistry 126. In addition, students majoring in chemistry must take either Physics 124 and 125, or Physics 126, 127, and 228; Mathematics through courses 126 or 128; and attendance during junior and senior years at 12 departmental seminars. Completion of at least one course credit in independent research (or completion of a summer research experience) is strongly recommended for students planning careers in chemistry.

Requirements for a Physical Science Teacher Major (with a Chemistry Concentration)

A chemistry major who wishes to teach chemistry in schools (5-12) must hold a valid Minnesota teaching license in physical science with a chemistry concentration. In addition to the chemistry major, additional science courses and the professional education sequence are required. Interested students should consult with a faculty advisor in the Education Department for details of requirements and available options. A physical science teaching minor is available.


St. Olaf College is accredited by the American Chemical Society through its Committee on Professional Training. Prospective majors in chemistry who expect to comply with the minimum requirements of the committee will take the following courses: Chemistry 125 (or 121 and 123), 126, 247, 248, 253, 254, 255, 256, 357, 371, 378, 379, 382, 386, and at least 1.25 additional laboratory credits selected from 373, 374, 375, 380, 384 (or 391: Bioanalytical), or 398. The Chemistry/Biology integrated course sequence (Chemistry/Biology 125, 126 and 127) may be substituted for Chemistry 125 and Chemistry 126. In addition, ACS-certified majors are required to take two mathematics courses beyond calculus II (Mathematics 126 or 128). This requirement is typically fulfilled by taking Mathematics 220 and one of Mathematics 226 or 230.

Students planning graduate work in chemistry should complete most of these courses, even if they do not fulfill all of the requirements for ACS certification. In particular, students interested in graduate school should take Chemistry 386 by the end of the junior year so that they have taken the background courses relevant to the Chemistry Graduate Record Examination prior to fall of the senior year, when that examination is typically taken.


The Chemistry Department seeks to encourage and recognize students who give evidence of creative and independent scholarship. A variety of opportunities are available for students to take a much greater responsibility for setting their goals and realizing the achievements of their education. Going beyond the regular course work, which introduces the theory and practice of chemistry, distinction challenges students to raise questions worthy of scientific investigation. Opportunities for distinction projects include, for example, summer research either on or off campus, Level II Independent Study (Chemistry 298), Level III Independent Research (Chemistry 398), Advanced Laboratory (Chemistry 375), and faculty-approved literature research projects. All projects for distinction will be considered on a case-by-case basis.

A full description of the distinction process is available at index.html.


St. Olaf chemistry majors have a number of options for special study, both on campus and elsewhere. On-campus programs that may include chemistry topics include concentrations in biomolecular science, envrionmental studies, neuroscience, and biomedical studies. Off-campus programs include the cooperative B.A.-B.S.E. Engineering Programs at Washington University in St. Louis and the University of Minnesota, where students may earn a degree in engineering, the Oak Ridge Science Semester, and the study of medicinal chemistry on an Interim abroad program to Jamaica. Internships in local industrial settings are another way to take college learning to another level. Consult the International and Off-Campus Studies Office for information on each of these programs.
