exchange coalescence, D2SO4

I have two questions:

1. Does anyone know of any software (preferably free) for the analysis of
temperature studies of chemical exchange? We would like to use it to model
an exchange and determine the coalescence temperature / energy barrier for
a conformational exchange phenomenon.
2. Does anyone have any experience with D2SO4 (deuterated conc. sulfuric
acid) as an NMR solvent? In particular, we need a good reference standard
for both 1H and 13C which is not digested by the solvent. We are using a
standard 5 mm tube with a teflon liner, and would prefer an internal standard.

Thank You,

Neil
