Dear Renjith,
you can calculate these as well of course. Below you will find
some coordinates for TMS. We used these e.g. in
Ll. Armangué, M. Solà and M. Swart
"Nuclear shieldings with the SSB-D functional"
J. Phys. Chem. A 2011, 115, 1250-1256
http://dx.doi.org/10.1021/jp108327c
And reference values for chemical shieldings can be obtained
at many places, e.g.

> Dear Friends,
> I have calculated the SCF GIAO magnetic shiedling tensor (ppm) in DMSO
using Gaussian09 for a chalcone derivative at b3lyp/6-311g++(d,p) level. In
order to calculate 1H and 13 C NMR chemical shifts values theoretically, I want
to know the values of absolute shielding constants of hydrogen and carbon.
Anyone Please help me.
