The paper presents splittings and q factors in the NaK D 1
state, directly measured from the electric
radio-frequency-optical double resonance RF-ODR in laser-induced fluorescence LIF for a number of
vibrational states v 122 with definite rotational levels J between 7 and 46. Permanent electric dipole
moment values d have been obtained by measuring in LIF spectra the relative intensities of ``forbidden''
lines caused by dc Stark effect induced e/f mixing in the 1
state, with their subsequent processing, which
allowed us to obtain the q/d ratio. A possible influence of the hyperfine structure on the RF-ODR signal and
relative intensities has been calculated, showing that this influence can be neglected. The q(v) values exhibited
a decrease from q(1) 1.529 10 5
cm 1
to q(22) 1.171 10 5
cm 1
