The hyperfine structure of the63CuF C1Π –X1Σ+ transition has been studied by laser-induced fluorescence in the sub-Doppler regime. Splittings of the ro-vibronic lines due to interactions with the copper (I = 3/2) and fluorine (I = 1/2) nuclei are observed in the P, Q, and R branches. The various contributions arising from magnetic dipole and from electric quadrupole interaction are specified. Parity dependent and independent terms are required to explain the dissimilar splitting patterns in the Q and the P/R branches. Hyperfine parameters for the C state of copper monofluoride are reported for the first time.

Experimental and theoretical work has been carried out on the hyperfine structure of the 4ƒ 6 7 F ground multiplet of samarium. Hyperfine structure intervals have been measured in the levels J = 1, 2, 3 and 4 for both odd isotopes 147 Sm and 149 Sm by the method of atomic beams. These intervals have been fitted to magnetic dipole and electric quadrupole interaction constants. Further measurements at high magnetic field by the method of triple resonance have led to the evaluation of the nuclear magnetic dipole moments of the two isotopes. It is shown that a calculation of the breakdown of L-S coupling and of second order corrections, off-diagonal in J , is necessary for an interpretation of the spectrum. The application of these corrections is facilitated by the formulation of an effective Hamiltonian, and the whole problem is treated step by step as a practical example of the use of tensor operator techniques. The spectrum is described in terms of a few overdetermined parameters, and in particular three radial parameters are evaluated. They are defined by the operator describing the magnetic field produced by the electrons at the nucleus: T ( e ) 1 = 2 β ∑ i ⁡ { < r l − 3 > 1 i − < r s C − 3 > √ 10 ( s C 2 ) i 1 + < r s − 3 > s i } . Their values are: < r i -3 > = 6.39 0 6 a 0 -3 , < r 5 C -3 > = 6.5 13 12 a 0 -3 , < r 5 -3 > = -0.20 8 6 a 0 -3 . The most important result is a precise determination of the nuclear magnetic moment of 147 Sm. It is μ I 147 = -0.807 4 7 n. m., uncorrected for diamagnetism. Also the ratio of the dipole interaction constants is A 1 147 / A 1 149 = 1.2130 5 2 for all J , and there is no observable Bohr-Weisskopf anomaly. It is shown that relativity is a plausible explanation for the non-vanishing of < r 5 -3 > in the contact term, but this explanation is not conclusive because the effect of relativity cannot be distinguished from that of configuration interaction in any part of the dipole interaction. The values of < r i -3 > and < r 5 C -3 >, which differ from each other, are compared with the value of an < r -3 > integral calculated by other workers. From the quadrupole interaction a value of –½ e 2 Q 147 < r Q -3 > = 149· 40 86 Mc/s is obtained and with less precision a value of Q 147 = -0.2 2 0 barn, uncorrected for shielding effects, is deduced. The ratio of the quadrupole moments is Q 147 / Q 149 = -3.460 3 1 , on the assumption that this ratio is the same as that of the quadrupole interaction constants.

Abstract The spin Hamiltonian parameters of 55Mn2+ in cubic ZnS have been determined by means of EPR and central-ion ENDOR, using Ka-band (35 GHz) microwaves. For the first time a value for the spherical electric quadrupole interaction of Mn2+ incorporated in a single crystal has been found. Also the ligand hyperfine interaction and the electric quadrupole interaction of the twelve Zn67 nuclei nearest to Mn2+ have been determined by means of ligand ENDOR.
