One of the primary questions chemists ask is “What is this substance?” Early answers to this question focused on composition or elemental analysis as structural arrangements were assumed to be unknowable. With the introduction of structural theory in the last half of the nineteenth century chemists began to look for evidence of the constitution or actual arrangement of atoms in molecules. Early evidence was based on wet chemistry methods, analogy, and derivatives. In current articles, evidence for structural arrangement is very instrumental – primarily IR, NMR, and MS. This presentation will compare specific examples of structural determination from the literature over a number of decades, as well as examples of how structural evidence in the literature has changed the way structural determination is taught in the undergraduate curriculum.

The University of Central Oklahoma (UCO) Chemistry Department has 200 chemistry majors with a range of post-graduation goals. A small percentage of these students end up in graduate programs in the chemical sciences each year. We have identified several factors that correlate with students’ eventual success in a graduate program. These include: participation in undergraduate research, either in the department or in a summer REU, active membership in the department Chemistry Club, attendance at a regional or national chemistry meeting, and a successful mentoring relationship with one or more department faculty. We will also discuss some of the traits of graduate-school bound students, and we will elaborate on interviews with some of our recent graduates.
