ACADEMIC QUALIFICATIONS
Research Associate: from 1993 to APR-2006. Ph.D. (chemistry); Indian Institute of Science; June 1993. Thesis title:Coordination Chemistry of Cyclotriphosphazenes.
Research Supervisor: Prof. S.S. Krishnamurthy. M.Sc. (Chemistry); Madurai Kamarajar University; I class; 1986. B.Sc. (Chemistry); Madurai Kamarajar University; I class; 1984.
Jun 1994- working with Professor ROBERT R. HOLMES on the HYPERVALENT COMPOUNDS OF SILICON AND
Apr 2006 PHOSPHORUS as a Postdoctoral Research Associate. The work involves
* The conformational/orientational study of penta coordinated phosphorus compounds
* Syntheses and structural study of phosphoranes based on biologically relevant
Carbohydrates and Nucleosides
* The hexa coordination on phosphorus (nature, strength and conditions)
* The penta/hexa coordination in silicon
Sep 1992- worked in the field of PHOSPHAZENE POLYMERS which is an important area in
May 1994 fire-retardant polymers. Two new kinds of soluble and easily modifiable but low
molecular weight chlorocyclophosphazene polymers and several derivatives of them
were synthesized and characterized. They were found to be highly
fire-retardant and thermally stable.
Aug 1986- worked on the coordination chemistry of cyclotriphosphazenes Group VI metal carbonyl
Aug 1992 complexes and palladium chloride complexes of various cyclotriphosphazene derivatives
were synthesized and characterized using spectroscopic (IR and 1H, 31P & 13C NMR)
techniques and single crystal X-ray crystallography. In this study, the modifiabl
nature of the phosphazene ring nitrogen-metal bond and a novel palladium assisted
hydrolysis of diazaphospholane ring have been demonstrated with structural evidences.

Windows; Little Macintosh). Have some UNIX/Linux knowledge.
Writing programs in FORTRAN. (Little C and Basic).
XTALDB.FOR ** To handle the recent KappaCCD's high output of datasets, this small database program has
been written. It stores some sample, cell and data information in ascii database and currently searches on cell, formula, crystal code.
Also it generates summary for: Space Groups, User/Group and Annual data.
XRAYACS.FOR ** CAD4 Single crystal X-ray data processing (Intensity calculation, LP correction & absortion corrections; either F or F2). More than 1500 lines.
SELECT.FOR ** To select strong reflections in desired angle range for refining the cell.
CHIACS.FOR ** For selecting reflections for PSI data collection (upto orthorhombic, additional octants can be searched).
DATAFALL.FOR ** To study the fall of intensity as a function of Theta.
FOFC.FOR ** To convert the CIF format Fo-Fc output of SHELXL-93 to three reflections per line for WINWORD.
CHNACS.FOR ** Calculation of elemental % from Empirical Formula
NMRTC.FOR ** Calculation of activation energy from NMR Tc (Coalescense Temperature) and frequency difference; it can back calculate where the Tc will be
for peaks for which Tc was not observed but activation energy has been calculated from other peaks.
