• Zeeman patterns of the nuclear Quadrupole resonance line of I^<127> were studied with a single crystal of iodine at medium and weak magnetic fields. The asymmetry parameter of coupling, η, and the angle between bond axis of the iodine molecule and crystallographic c axis, ψ, were determined from the pattern at a medium magnetic field of about 120 gauss. The result was η=-0.16±0.01 at 14℃ when crystallographic b axis was chosen as χ axis and ψ=31°38'±60'. The absolute value of ηis in accord with the value obtained by the two resonance frequencies, i.e. 0.151±0.001 at 11℃, ψ agrees with that obtained by the X-ray diffraction, 32°4'. At a weak magnetic field, Zeeman patterns of the fine structure of iodine were examined at three directions of magnetic field against the iodine crystal, i. e. the b axis, the c axis and the direction of 60° from the b axis in the bc plane. Behaviour of the superregenerative detector used for these N. Q R. measurements was studied and the observed shape of the resonance line is discussed.
