The department is well equipped to carry out state–of–the–art research with facilities such as an NMR centre (300, 400 and 600 MHz instruments), a gas chromatograph–coupled mass spectrometer, atomic absorption spectrometers, mid–IR spectrometers, Fourier Transform IR interferometer, UV–visible spectrometers, X–ray generators and single crystal diffractometers (serial and CD detectors), spectropolarimeter and workstations for both thermal and electrochemical analyses.
Research Services Available
NMR Unit
The NMR unit houses three Bruker Avance III HD spectrometers; a 300MHz Nano, 400MHz Ultrashield and a 600MHz Ascend equipped with a LN2 cryprobe. These are used in combination to record spectra for compounds containing magnetically active nucleii (1H, 13C, 19F, 31P, etc) and include additional 2D spectra (COSY, HSQC, HMBC, DOSY, TOCSY and others) routinely recorded by submission from internal and external users for characterisation and quantification where appropriate

X–ray Diffraction
Huber Imaging Plate Guinier Camera 670. A compound in the form of a powder is exposed to an X–ray beam. The angular positions and the intensities of the diffracted beams are recorded, producing a characteristic pattern.
Nonius Kappa CCD diffractometer and Bruker Kappa Apex II DUO CCD diffractometer. A single crystal is exposed to a beam of X–rays and the intensities diffracted by the crystal are accurately measured. Subsequent processing of the data and computation leads to the determination of the molecular and crystal structure of the material.
