Abstract
Fluorobenzenensulfonamides of Formula I ##STR1## wherein m means the number 0, 1, 2, 3, or 4, n means the number 0 or 1, and Y means the residue of an aminocarboxylic or aminosulfonic acid, with the proviso that m and n are not to stand simultaneously for the number 0 and, if desired, the acid groups are present in the form of their amides or in the form of salts with organic or inorganic bases, are suitable for use as NMR diagnostic aids.
