Chiral Molecules. About The Authors. . These Powerpoint Lecture Slides were created and prepared by Professor William Tam and his wife Dr. Phillis Chang. . . Professor William Tam received his B.Sc. at the University of Hong Kong in 1990 and his Ph.D. at the University of Toronto (Canada) in 1995. He was an NSERC postdoctoral fellow at the Imperial College (UK) and at Harvard University (USA). He joined the Department of Chemistry at the University of Guelph (Ontario, Canada) in 1998 and is currently a Full Professor and Associate Chair in the department. Professor Tam has received several awards in research and teaching, and according to . Configuration. While conformational isomers are . interconvertable. through rotations about single bonds, . configurational. isomers require bond-breaking and reforming for . interconversion. .. Stereoisomers. LCMRC researchers are exploring the recently discovered ferronematic liquid crystal phase, revealing a dramatic polar magneto-optical response to externally applied magnetic field in millimeter-size droplets on glass slides, like the one shown. With one sign of field normal to the slide the molecules stand up also normal to the glass but for the other sign, shown in the image, the molecules flip over, a reorientation heralded by the dramatic appearance of birefringence above a threshold field. This response represents a record-large magneto-optical effect. . CHE 6416. Michael Evans. 1. How does Microwave relate to other spectroscopies. Different types of motion. Translational. Vibrational.
