The spectroscopic section, comprise on
over 20 laboratories, of the ICCS is one of the finest in
the world. This section includes ten major sections equipped
with state-of-the art analytical, spctrocopic and chromatorgraphic
instrumentation which are not available in any single institution
in the world under one roof. The prominent among the spectropscopic
facilities is Nuclear Magnetic Resonance Spectroscopy, or
NMR. This is an important tool of the chemistry research
used for the determination of molecular structure. NMR spectra
are acquired on a special instrument called an NMR Spectrometer.
The instrument and concepts are related to those used for
Magnetic Resonance Imaging or MRI in medical diagnostics.
The technique is challenging to learn but wonderfully powerful
for the determination of organic and biochemical structure.
For organic structure determination, the two most important
types of NMR spectra are the proton and carbon spectra.
They give information about the number of hydrogen's and
carbons in a molecule and how those hydrogen's and carbons
are connected together as well as information about functional
groups. NMR complements IR for determination of structures
of organic compounds. Remember IR spectra help identify
functional groups in a molecular structure.
Mass Spectrometry
The ICCS has a world class
mass sepctometric facility Equipped with six large magnetic
sector mass Spectrometers including Jeol HX110 (largest commercially
available mass spectrometer), Jeol JMS 600 mass spectrometers
(Two), Thermo finngan mass spectrometers, Jeol SX mass spectrometer,
Perkin Elmer LC-MS, Shimadzu GC-MS (Two), MAT 311, and MAT
312 and MAT 313 mass spectrometers. These machines are used
to study the molecular weight and composition as essential
tools for modern chemical and biocehemical science research.
Single-Crystal X-Ray Diffraction Facility
The ICCS has two state-of-the-art single-crystal
x-ray diffractometers (Siemens P4 and Bruker Enrauf-Nonius
Apex smart) which are used to determine the three diemensional
structures of complex organic molecules.
Other Spectroscopic Facilities
The other spectrometric facilities at the
ICCS include several FT-IR sepectrophotomeetrs (four), UV
spectrophotometers, CD-ORD, ELISA readers (three), Gas chromtographs,
elemental anlayzers, polarimeters, ICP for metal analysis,
PCR machines, etc.
