ESF Unveils New NMR Unit
SYRACUSE, N.Y. - The SUNY College of Environmental Science and Forestry (ESF) Friday will celebrate the installation of its powerful new nuclear magnetic resonance spectrometer. The unit is the first of its kind in Central New York.
The 600-megahertz spectrometer, known as an NMR, is a focal point of the college's state-of-the-art Edwin C. Jahn Laboratory. It allows scientists to examine the structure of molecules and put that knowledge to use in the development of new products.
The NMR came to Syracuse through a joint effort involving ESF, Syracuse University and the SUNY Health Science Center. All three institutions pooled their money to purchase the unit, with most of the $725,000 coming from ESF. At the time it was purchased, ESF also upgraded its less powerful 300-megahertz NMR.

NMR is the parent technology from which the widely used magnetic resonance imaging technology was developed. In effect, an NMR unit visualizes molecules in the same way an MRI unit creates an image of a human body. NMR allows the chemist to visualize a molecule by single atoms, providing exquisitely detailed structural information about complex molecules, both natural and man-made.
Chemists at ESF, SU and the HSC are using the new NMR to solve the following problems:
- understanding how HIV viruses defeat antibodies;
- explaining the chemistry of toxic shock syndrome;
- determining the structure of complex natural products such as insect pheromones;
- learning about the structure of bacterial components that can be used to make vaccines such as the haemophilus influenza vaccine that all children now receive;
- researching the structure of marine toxins-such as those produced during so-called red tide events-that can find their way to humans, causing severe illness or even death;
- investigating the chemical features needed for good lubrication;
The NMR unit at ESF is unusual because it can be used to analyze liquids, solids, and gels at very high magnetic field strength while most such machines work only with liquids.
The college will sponsor an open house from 2:30 to 4:30 p.m. Friday, May 7, adjacent to Room B18 in the Jahn lab. There will be a tour of the NMR facility and poster presentations explaining its uses.
