Rotational Transitions

The observation of the low lying rotational transitions J = 0 →1 of AgCl and J = 2→3 of AgBr resulted in improved quadrupole coupling constants: 107, 109Ag35Cl: e qν Q (35Cl) = -36,50 (10) MHz (ν=0,1); 107.109Ag79Br; e q0 Q(79Br) =297,10(15) MHz, e q1 Q (79Br) =297,65 (15) MHz. In con­trast to former measurements of KRISHER and NORRIS we obtained the following constants of 107Ag79Br: Y01 = 1943,6420 (50) MHz, Y11 = -7,0745(70) MHz, re = 2,393100(29) Å. The unknown rotational spectrum of AgJ was found. Measurements of the transition J = 3 →4 in four vibrational states resulted in the determination of the following molecular constants: Y01 = 1345,1105(25) MHz, Y11= -4,2389(30) MHz, Y21 = 1,70(80) kHz, Y0,=-0,2540(2) kHz; re = 2,544611 (31) Å; e q0 Q(127J) =-1062,17(40) MHz, e q1 Q(127J) = -1064,81 (40) MHz.

Abstract We describe a new type of laser-radiofrequency double-resonance experiment, which allows to determine not only the absolute value but also the sign of nuclear quadrupole coupling constants. This determination of the sign, which is essential for the comparison with calculated EFG tensors, is not possible with purely magnetic experiments. The m ethod has a high resolution and, because of the optical detection, also a high sensitivity. As an example, the quadrupole coupling constant for Pr3+ :YAlO3 was measured at 4.38 K and was found to be negative.
