We present experimental data on the electric permanent dipole moments d ,J and splittings
q factors in the quasidegenerate 3 1
e/f state of the NaCs molecule over a wide range of the
vibrational and rotational J quantum numbers by using the combination of dc Stark mixing
and electric radio frequency-optical double resonance methods. Within the experimental 3 1
state
ranged from =0 to 34, q values exhibited a pronounced decrease from 7.91 10-6
to 0.47
10-6
cm-1
, while d values varied between 8.0 and 5.0 D. Experimental evaluation yielded small
