The
FF values of acetic acid (No.1, 2) and butyric acid (No.3, 4) were in good agreement with those of iodine, while the
FF values of butanol were different from those of deuterated water (The
FF values obtained from the same number sample were compared). These results indicate that the diffusion path of carboxylic acid was similar to that of iodine, while the diffusion property of butanol was different from that of deuterated water.
