solvent temperature epsilon



 Dear All,
 I have a question regarding a Gaussian03 frequency job in a solvent
 at different temperatures.
 
Could someone tell me if the dielectric constant should be specify in the input file for each solvent and at the considered temperature, or if the value is automatically known?
 Do you have any bibliographic references to obtain these values ?
 Best regards
