Sutton, Sarah C.; Cleland, Walter E.; Hammer, Nathan I. – Journal of Chemical Education, 2017
This advanced undergraduate chemistry laboratory exercise takes advantage of the unique spectroscopic properties of the free radical chlorine dioxide to allow for a direct comparison of its symmetric stretch in both the ground and excited states. It incorporates several subject areas covered in an undergraduate chemistry degree (synthesis,…

Frey, E. Ramsey; Sygula, Andrzej; Hammer, Nathan I. – Journal of Chemical Education, 2014
This laboratory exercise introduces undergraduate chemistry majors to the spectroscopic and theoretical study of the polycyclic aromatic hydrocarbon (PAH), corannulene. Students explore the spectroscopic properties of corannulene using UV-vis and Raman vibrational spectroscopies. They compare their experimental results to simulated vibrational…

Scardino, Debra J.; Howard, Austin A.; McDowell, Matthew D.; Hammer, Nathan I. – Journal of Chemical Education, 2011
The physical chemistry laboratory is sometimes constrained to one semester, resulting in pedagogical deficiencies for the students taking the course. The use of a multidimensional laboratory exercise offers students the opportunity to encounter multiple experimental techniques and physical chemistry concepts while not sacrificing a significant…
