This department supervises the following degree programs: CHEMISTRY, Bachelor of Arts or Bachelor of Science, Master of Science, and Doctor of Philosophy; BIOCHEMISTRY, Bachelor of Arts or Bachelor of Science. Those students seeking graduate degrees may specialize in analytical, inorganic, organic, or physical chemistry, chemical education, chemical physics, or biochemistry.

The Department of Chemistry and Biochemistry offers four undergraduate degree programs in chemistry and biochemistry. One of these degree programs will be appropriate for the student who wishes to pursue a professional career in chemistry or biochemistry or for one who desires a strong undergraduate background in the central sciences of chemistry and biochemistry as preparation for other interests such as health-related professional schools, teaching, or sales. The undergraduate advisor assists the student in selecting courses, fulfilling degree requirements, and career counseling. The department has added honors-level courses to the curriculum. These courses will substitute for non-honors equivalents. Only qualified students may enroll in these courses. See the undergraduate advisor for details. Highly motivated undergraduate chemistry or biochemistry majors may be interested in conducting an individual research project under the supervision of a faculty member. Such students may wish to obtain a working knowledge of research methods in a specialized area, or simply desire familiarity with a wide range of research instrumentation and techniques. The department also has a very active chapter of the Student Affiliates of the American Chemical Society.

Students interested in a minor in chemistry should consult with the departmental advisor. A minor requires a minimum of 19 hours in chemistry with at least 4 of those hours being laboratory credit.

Chemistry. The undergraduate student may take courses leading to a Bachelor of Arts or a Bachelor of Science degree in chemistry. Either program offers a wide choice of minor subjects, not only in the College of Arts and Sciences, but in the other colleges as well. Consult the undergraduate advisor in the Department of Chemistry and Biochemistry prior to registration for a particular minor program. Introductory courses CHEM 1105, 1106, 1301, 1303, 1306, 3103, 3303, and 3402 cannot be counted towards a minor in chemistry. Courses with a grade of D cannot be counted toward fulfillment of requirements for a major or minor (including adjunct requirements and minors from other departments) in any program in this department.

The Bachelor of Science degree prepares a student for graduate school or a career as a professional chemist. This degree program is technically oriented, requiring greater depth of mathematics, physics, computer science, and chemistry than does the Bachelor of Arts degree. With the heavier chemistry requirement in the B.S. degree program, the student has fewer elective courses for other interests. Completion of the B.S. degree curriculum leads to automatic certification of a student as the recipient of a professional degree by the American Chemical Society. The minimum required for the B.S. is 133 hours and 130 hours for the B.A. degrees in chemistry. The minimum required for both the B.S. and B.A. degrees in biochemistry is 133 hours.

Chemistry Curriculum, B.S. Degree.

A total of 48 hours of chemistry is required.

*Adequate training in algebra, trigonometry, and analytic geometry is a prerequisite for calculus. The student in doubt about which mathematics courses to take in the first year must consult with the departmental undergraduate advisor.

**The science elective must be either BIOL 1401 (Biology of Plants) and BIOL 1402 (Biology of Animals) [or BIOL 1403, 1404 (Biology I and II)] or GEOL 1303, 1101 (Physical Geology) and GEOL 1304, 1102 (Historical Geology).

Biochemistry Curriculum, B.S. Degree. This degree program will prepare an undergraduate student for graduate study in biochemistry and related disciplines, for entry into medical or dental school, or for employment in industrial or governmental laboratories in which graduate training is not required. Completion of the B.S. degree curriculum incorporates a minor in biology.

A minimum of 40 hours of chemistry is required.

Residency Requirements. The Department of Chemistry and Biochemistry generally accepts transfer credits from other colleges and universities. However, to receive an undergraduate degree in either chemistry or biochemistry at least 25 percent of the hours in the major must be taken at Texas Tech. For a minor in the Department of Chemistry and Biochemistry, at least one of the courses past the freshman level must be taken at Texas Tech. All chemistry minors must complete a minimum of 6 junior or senior hours in the department.

Advanced Standing. The Department of Chemistry and Biochemistry will permit a student to receive credit for any courses in the curriculum if proficiency is demonstrated in that area by examination. Examinations for CHEM 1305, 1306, 1307, and 1308 are given the week before classes begin each semester. See the Coordinator of General Chemistry to schedule a time. Previous registration for these examinations is not required of students entering Texas Tech for the first time. Students who are enrolled must apply to the Dean of the College of Arts and Sciences for approval to take the examination. For all other courses, after having received approval from the Dean of the College of Arts and Sciences, it will be the responsibility of the student to petition the department chairperson for such examination(s) well before normal enrollment in the course.

Teacher Education. Students seeking a teaching certificate in chemistry are expected to earn a bachelor's degree (B.A. or B.S.) with a major in either chemistry or biochemistry. College of Education requirements for certification in chemistry and science are described in the "Teacher Education" section of this catalog.
