Abstract:
The P(5) branch features of the A (3)Φ(4)←X (3)Φ(4) (1,0) band near 628.2 nm of a molecular beam of iridium monofluoride, (193)IrF, were recorded field free and in the presence of a static electric field. The (193)Ir (I(1)=3/2) and (19)F (I(2)=1/2) hyperfine interactions in the A (3)Φ(4) (υ=1) and X (3)Φ(4) (υ=0) states were analyzed. The permanent electric dipole moments, μ(el), for the A (3)Φ(4) (υ=1) and X (3)Φ(4) (υ=0) states were determined to be 1.88(5) and 2.82(6) D, respectively, from the analysis of the observed Stark shifts. A comparison of the electric dipole moments for IrC, IrN, and CoF is presented.

Theoretically, studying electric dipoles leads to understanding why the resultant electric forces around us are weak. Since electric forces are strong, remnant net charges are rare. Hence, the interaction between dipoles helps us understand electrical interactions in...
