化学系在其研究生课程中提供了出色的研究和教育机会，从而获得了理学硕士或博士学位。研究生学位的核心是与导师共同进行的研究。该计划需要24小时的课程工作，并且学生将获得博士学位。成功完成文学研讨班（第四学期）和研究会议（第五学期）后的候选人资格。该计划强调整个科学家的发展。化学系的子专业研究领域包括：光化学，分子光谱学，药物化学和药物发现，材料化学和纳米技术，有机金属，物理有机，生物有机，聚合物和理论化学以及化学动力学。
Masters Degrees can be obtained by graduate coursework only, MS (non-thesis), or by a combination of graduate coursework and research culminating in a written thesis, MS (thesis). These degree programs may be pursued on a full-time or part-time basis with entry to the program possible in August or January. The part-time MS (non-thesis) remains a particularly popular option for chemists with bachelors degrees who are employed locally in St. Louis and are looking to upgrade their qualifications. Contact us by e-mail or phone for an application package, for more information or to arrange a visit to campus. The Chemistry and Biochemistry department has a strong research emphasis as well as a dedication to teaching, but is of medium size allowing substantial interaction between faculty and students. There is an international make-up to the faculty and postdoctoral fellows, and there are graduate students presently in the department from the United States and abroad. The department is very well equipped with modern instrumentation and computing resources. These include outstanding NMR, X-ray and mass spectrometry facilities, with two 300 MHz and one 600 MHz NMR spectrometers, two single-crystal and one powder X-ray diffractometers, a JEOL M station and GC-MS facilities. Areas of research specialization include the traditional areas of Inorganic, Organic, Physical chemistry, and Biochemistry, as well as organometallic, supramolecular, interfacial and computational chemistry, laser spectroscopy and the study of new materials. Former graduates are employed in research positions in the chemical and pharmaceutical industries, in academic positions, and in other areas such as high-tech computer applications.
