• Single crystals of K_2CuCl_4・2H_2O and (NH_4)2CuCl_4・2H_2O were examined at 7 different frequencies of microwaves (from 5.4 mrn to 6.2 cm wavelengths). If there were no exchange coupling, two absorption peaks would be expected corresponding to different g-values of two dissimilar Cu^<++> ions in unit cell. Experimentally, however, only one peak can be observed at, longer wave-lengths, though the line width remarkably increases with decreasing wavelengths. At the wave-length of 5.4 mm two isolated peaks can be observed. These facts can be interpreted in terms of exchange interaction between dissimilar ions. The exchange energy estimated from these data is greater than 0.1 cm^<-1>. On the other hand, the width for the c-axis, where the situations of two Cu^<++> groups are identical, decreases with decreasing wavelengths to aboutthe value 1/4 of that at long enough wave-length. According to the treatment by Anderson and Weiss, this result may be explained by their "10/3" effect.
