艺术与科学学院的文学士学位课程不是专业课程，可以由不打算在化学或相关科学领域从事研究生工作但希望拥有比化学辅修课程更强大的化学背景的学生选出程序。BA课程还提供与健康相关的化学，环境化学，地球化学或化学管理选项的有用组合。学生可能会在大三时从BS转换为BA计划，反之亦然，因为两者的基本要求相同。正在进行文学学士学位课程并在近期决定就读化学，生物化学或相关科学的研究生的学生，应与部门顾问之一交谈，讨论可选的课程材料，这将为他们准备研究生课程做好准备。
Lehigh’s B.S. degrees in chemistry are designed to provide students with a broad background in chemistry while simultaneously offering opportunities to explore cutting-edge, multidisciplinary research problems. Several courses are offered in the core and in the customizable curriculum that have integrated interactive group approaches to study, such as studio in introductory chemistry, workshops in organic, and project groups in analytical and physical laboratories. Working in groups enhances learning and student satisfaction.<br>Research opportunities are available in areas such as materials chemistry, biological chemistry, surface chemistry, and nanoscience and technology, along with traditional disciplines of analytical, inorganic, organic and physical chemistry. Research is an option that 70 percent of the majors in chemistry and biochemistry select. Faculty in chemistry welcome undergraduates into their research groups. Students work on important projects in areas that have a direct impact on society: New diagnostic assays for HIV antigens, pharmaceuticals for rage suppression, drug delivery by novel liposomes, new catalysts for synthesis of fuels and smart surfaces are only a few of the research projects available to undergraduates.<br>The B.A. program in the College of Arts and Sciences is not a pre-professional program and may be chosen by students who do not plan to do graduate work in chemistry or allied science but want a stronger background in chemistry than is provided in the chemistry minor program. The B.A. program also affords a useful tie-in with health-related chemistry, environmental chemistry, geochemistry or chemistry management options. Students may transfer from the B.S. to B.A. programs or vice versa as late as the junior year, since basic requirements are the same for the two.<br><br>
