摘要: Abstract The 13 C-NMR chemical shifts for all carbon atoms in a series of n -alkyl esters benzophenone-4-carboxylic acid various chain lengths have been measured as function the stoichiometric solute concentration CCl 4 and CH 3 CN solvents. Concave sharp downward curvatures were observed CN, suggesting that aggregation occurs this polar solvent, whereas only small linear effect was . C spin-lattice relaxation measurements gave further support to idea aggregate formation. Possible reasons structure aggregates are discussed well.
