Dr.S.Aravamudhan joined the Department of Chemistry,
North Eastern Hill University,Shillong on the 15th April 1985 . The curriculum vitae of Dr.Aravamudhan , currently the Principal
Investigator in this CSIR Project, can be displayed from the LINK provided by a CLICK HERE
In this web site all the relevant particulars about this CSIR
project are covered and they all sorted out in the various pages of this site which have hotlinks for convenience of navigation.
There is a page where in an announcement about the requirement for a staff to be appointed in this project and from this advertisement
the interested candidate should apply aon plain paper ,as early as possible, to the principal investigator.

TITLE OF THE PROJECT
SHIELDING PARAMETERS OF NUCLEI: FACILITIES FOR
THE EXPERIMENTAL DETERMINATION AND CALCULATION BYTHEORETICAL PROCEDURES-TO OBTAIN INFORMATION ON CRYSTAL
STRUCTURES AND MOLECULAR ELECTRONIC STRUCTURES
The experimental part of the project is the construction of a Magic
Angle Sample Spinning accessory to the AC 300 High Resoltion (solution) Spectrometer. It wpould be possible to obtain solution-like
spectra from the POWDER specimens by spinning the sample about an axis at Magic Angle to the applied field direction. Illustration
below:

The Magic Angle Sample Spinning (MASS) accessory can be made
available in the HR liquid state spectrometers simply by providing a suitable probe without having to change the Transmitter-receiver
part of the spectrometer to the High Power solid state NMR spectrometer models. This enables obtaining MASS spectra for a
variety of the nuclei as is available in a Multi-nuclear liquid state HR NMR(AC 300) spectrometers. To obtain better sensitivity
for the less abundant nuclei,the MASS spectra are obtained usually with additional sensitivity enhancement by the solid-state
'cross-polarisation' (CP) techniques and such experiments are known as CPMASS experiments. But, adding this feature
for CP techniques would require escalating the spectrometer specifications to that of SOLID-STATE NMR models which is not
as simple as providing a simple probe assembly only.
The Calculation aspects of the Shielding parameters with
emphasis on the efforts made by the Principal Investigator (PI) till now are compiled in the webpages of a Website:
