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

The [11.9]Omega = 3/2 <- X (2)Pi(3/2)(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 F-19(I = 1/2) and Pt-195(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, (mu) over right arrow (el), of 2.47(11)D and 3.42(6)D for the [11.9]Omega = 3/2 and X-2 Pi(3/2) states, respectively. The observed trend in (mu) over right arrow (el) for the PtX (X = C,N,O,S and F) series is discussed and a comparison with IrF made. (C) 2012 American Institute of Physics.
