The Chemistry Department at Moravian College provides students with a fundamental understanding of the concepts of chemistry and their application to advanced problems. Beginning in the general chemistry course, the program emphasizes exploration of chemical principles through hands-on experience with chemical instrumentation. All students have the opportunity to work with faculty members on original research projects that range from theoretical physical chemistry to biochemistry. The department is on the approved list of the American Chemical Society. Graduates who complete appropriate requirements of the society receive a bachelor's degree certified by the society.

Many chemistry majors go on to graduate school in chemistry, medicine, dentistry, and biological sciences. Others pursue careers in industrial or governmental research, technical sales, medical technology, technical law, library work, or secondary school chemistry.

The Major in Chemistry

The major in chemistry consists of nine course units above Chemistry 110, including Chemistry 113-114, 211-212, 220.2, 222, 331-332, and 370.2. The remaining course is selected by the student with the approval of the major advisor. Chemistry majors also must take Mathematics 170 (or its equivalent sequence Mathematics 106-166), Mathematics 171, and Physics 111-112.

The Minor in Chemistry

The minor in chemistry consists of five course units: Chemistry 113-114, 211, 222, and either 212 or 331.

The Interdepartmental Major

The six courses that compose Set I of the interdepartmental major in chemistry include Chemistry 113-114, 211, and 222. The remaining courses in chemistry and the six courses of Set II are selected by the student with the approval of the advisor.

Departmental Recommendations

Students planning graduate work in chemistry are advised to take additional advanced courses in chemistry, mathematics, computer science, physics, or biology.

Students wishing to obtain a bachelor's degree certified by the American Chemical Society are required to take a total of 13 chemistry courses. These must include those required for the basic major, plus Chemistry 311, Chemistry 327, Chemistry 341, and one additional 300-level chemistry course. Students are encouraged to use independent study (Chemistry 381) or Honors (Chemistry 400) to fulfill the final course requirement.

Students seeking certification to teach chemistry in secondary schools complete the requirements for a departmental major and the requirements for certification described under education and science education. Students interested in combining chemistry and general science certification should consult the requirements for general science certification under science education.
