Camden Group Attended International Confrence on Raman Spectroscopy
The Camden group attended the International Conference on Raman Spectroscopy held at Boston, MA from August 8 to 13. During the conference, Dr. Camden presented a talk on Wavelength Scanned Surface Enhanced Hyper Raman Spectroscopy. Chris Bennett and Vighter Iberi both presented posters at the student poster session.
Bennett collaborated with Camden and discussed recent advances in Hyper Raman spectroscopy in his project. Topics include a discussion of wavelength-scanned surface enhanced hyper Raman spectroscopy of various active molecules. Unusually high Hyper Raman signal has been produced on silver colloids from incident laser power as low as 106 W/cm2 average power, as shown in the figure below. This has enabled the discovery of a new two-photon accessible resonant mode in Rhodamine 6G (abstract provided by Bennett, picture on the left).
The goal of Vighter, Camden and Guiton’s project is to correlate the optical measurements of nanostructures generated by the surface plasmons using Resonant Rayleigh Scattering, with high resolution structural information obtained by using Scanning Transmission Electron Microscopy (STEM). This technique will also reveal the different localized surface plasmon modes in the nanostructure as well as the relationship between the optical surface plasmons and the plasmons generated from the inelastic scattering of the electron beam. The measurement of the surface plasmon excitations in a STEM is called Electron Energy Loss Spectroscopy (EELS)(abstract provided by Vighter, picture on the right).
Dean of the College of Arts and Science Bruce Bursten has been named to the American Chemical Society (ACS) fellows program. The program began in 2009 to recognize and honor ACS members for their outstanding achievements in and contributions to the science, the profession, and service to the society. Bursten, who was president of ACS in 2008, conducts research in inorganic chemistry, focusing on the correlation of theoretical and experimental electronic structural data with the bonding and reactivity patterns of metal-containing molecules. The 192 new ACS Fellows will be honored at the society’s fall national meeting in Boston later this month. Additional information about the program is available at
