Recently the O'Brien group {\textbf{265}} 39, 2011.} reported on the field-free detection and analysis of the [11.9]$\backslash Omeiga=3/2-X2\Pi 3/2$ band system of PtF using intracavity laser absorption. The hollow cathode condition limited the spectral resolution, which was insufficient to fully resolved the hyperfine splitting of $^1^9^5$Pt (I=1/2) and $^1^9$F (I=1/2). Here we report laser-induced fluorescence spectra of the 1-0 and 0-0 bands of the [11.9]$\backslash Omeiga=3/2-X2\Pi 3/2$ transition of PtF, obtained at near natural linewidth resolution (FWHM ~40MHz) using supersonic molecular beam techniques. The spectra show a complex, cleraly resolved hyperfine structure which has siginificant contributions from magnetic term in $^1^9^5$Pt and $^1^9$F. The spectra of $^1^9^4$PtF, $^1^9^5$PtF, $^1^9^6$PtF, $^1^9^8$PtF isotopogues have been assigned and analyzed. The electric field induced dependence of the R(1.5) branch of the $^1^9^5$PtF isotopogue was analyzed to produce permanent electric dipole moment, $\mu$, of 3.45 D and 2.32 D for the $X2\Pi 3/2$ and [11.9]$\Omega =3/2$ states, respectively. A comparision with Ab Initio prediction {\textbf{23}} 564, 2001.}$,$, {\textbf{39}} 2023, 2000} will be given.
