摘要: Abstract A nuclear magnetic resonance study of the 35Cl quadrupolar interaction in single crystal and polycrystalline ammonium perchlorate (APC) at 2T 7T yields a value = 320(20)kHz =0.80(10) 300 K. The temperature dependence is approximately -0.1 kHz /kat 340K, zero K, +3 kHz/K near 40 K quadrupole coupling passes smoothly through 20 At 4.2K 50kHz, presumably opposite sign to that 300K, with finite dependence. Anomalies 200 are observed satellite behavior. former doubling line □H increased separation b □H, which exhibit time anomaly frequency arrest for range about 5
