• The Zeeman splitting for Cl^<35> quadrupole resonance in a single crystal Ba(ClO_3)_2・H_2O in a high magnetic field (about 6000 oe) was studied in detail by using the proton signal enhancement due to a crossing of the quadrupole resonance frequencies of chlorine nuclei and the magnetic resonance frequencies of protons. The parameters of Ba^<135> and Ba^<137> quadrupole resonances in a Ba(ClO_3)_2・H_2O were obtained, using the crossing technique: 1 ν(Ba^<137>)=13.18±0.01 Mc. ν(Ba^<135>)=8.55±0.01 Mc. at 15.5℃, Q^<187>/Q^<135>=1.542±0.002 2 Asymmetry parameter, η=0.480±0.004 3 The direction angles of the principal axes x, y, z, of field gradient tensor with respect to crystal axes a, b, c, are (123±3°, 90°, 30±3°), (33±3°, 90°, -60±3°), and (90°, 0°, 90°) respectively. 4 The temperature coefiicient of frequency, 1/ν_Q・dν_Q/dT, is 1.04×10^<-3> deg^<-1> for the temperature range from 20℃ to 70℃.
