The permanent electric dipole moment and hyperfine interactions in platinum monofluoride, PtF.

The [11.9]Ω = 3/2 ← X 2Π3/2(0,0) and (1,0) bands of platinum monofluoride, PtF, have been recorded field-free and in the presence of a static electric field. The 19F(I = 1/2) and 195Pt(I = 1/2) magnetic hyperfine interactions have been analyzed and compared with predicted values obtained using atomic information and a proposed molecular orbital correlation diagram. The optical Stark shifts were analyzed to produce the permanent electric dipole moments, μvector _el, of 2.47(11)D and 3.42(6)D for the [11.9]Ω = 3/2 and X 2Π3/2states, respectively. The observed trend in μvector _el for the PtX (X = C,N,O,S and F) series is discussed and a comparison with IrF made. [ABSTRACT FROM AUTHOR]
