Instrumentation

Located in Hutchison Hall, the chemistry department's modern instrumentation facility provides a stimulating work environment and is equipped with a wide variety of sophisticated research instrumentation for spectroscopy, analysis, and computation.

The departmental instruments are used by students and faculty in a hands-on way, and most are available 24 hours a day. The opportunity for students to use state-of-the-art instrumentation represents one of the unique strengths of our department. We have acquired the most up-to-date equipment through a series of instrumentation grants from the National Science Foundation, the National Institutes of Health, and other donors.

Many of our research instruments, such as NMR and Mass Spectrometers and the new Laser Raman facility, are available to researchers outside the department.  For more information about the NMR and MS instrumentation, contact Terry O’Connell (toc@chem.rochester.edu). Contact David McCamant (mccamant@chem.rochester.edu) for more information about the new Laser Raman facility.

Many of the department's instruments are highly specialized. Some have been designed and built on site or substantially modified from commercially available instruments to meet the specific needs of the department's researchers.

Staff members are available to train new users, help with troubleshooting, and offer advice on special problems, but the actual measurements are carried out by the individual researchers and the students they mentor.

Laser Systems

The department maintains laser systems for absorption, fluorescence, and Raman spectroscopies, nonlinear four-wave mixing, electro-optic sampling, time-resolved electron diffraction, photoelectron spectroscopy, temperature-jump studies, photoacoustic calorimetry, and the initiation of photochemistry:

  • Two kHz regeneratively amplified femtosecond titanium:sapphire lasers, one with an optical parametric amplifier for generation of continuously tunable UV, visible and infra-red femtosecond pulses
  • Transient absorption systems based on a picosecond Nd:YAG laser and a nanosecond excimer-pumped dye laser
  • Picosecond time-correlated single photon counting fluorescence system based on a Nd:YLF-pumped cavity-dumped dye laser
  • Laser Raman facility
  • Nd:YAG/dye laser system
  • Associated optical instruments: monochromators and spectrographs, fast multichannel plate photodetectors, and state-of-the-art, highly sensitive array detectors (CCDs and photodiode arrays)
