Dear Netters,

      I am looking for the experimental data or ab initio calculations (HF) 
of C2H4F2 (1,2-difluoroethane) deltaE(trans-gauche) in conformational 
equilibrium, considering several solvents, e.g.,
	_____________________________________________________
	medium		  EPS		deltaE(trans-gauche)
	-----------------------------------------------------
	vapor		  1.0		  ?
	cyclohexane	  2.0		  ?
	carbon disulfide  2.6		  ?
	diethyl ether     4.3     	  ?
	ethyl acetate     6.0		  ?
	pure liquid        ?		  ?
	acetone           35.9            ?
	water             78.5            ?
	----------------------------------------------
Could anyone please tell me where I can find them (papers, database, etc). 
Thanks in advance for any suggestion.
