The type of H-NMR spectra observed for S=PF2H and other inorganic molecules similar to this
The everything OP and  orthocresol discussed in the comment session is in this reference book (Ref.1). I include its PDF file (Ref.1) for benefits of OP and future readers. An example of coupling is depicted in the following figure (from Ref.2):

This spectrum is qualified as other inorganic molecules similar to $\ce{S=PF2H}$ molecule. What I want to show is alike different coupling constants in $\mathrm{^1H \ NMR}$ due to the molecular structure, bond distance, etc., the coupling constants in $\mathrm{^{31}P }$ and $\mathrm{^{19}F \ NMR}$ are also changed as well. For instance, $^1J_\ce{HH}$ is $17$-$\pu{20 Hz}$ in $\mathrm{^1H \ NMR}$ organic compound. However, $^1J_\ce{PH}$ is $\pu{836 Hz}$ for this particular molecule ($\ce{PF2H(^{15}NH2)2}$) while $^2J_\ce{PH}$ is $\pu{11.8 Hz}$ for same molecule (c.f., avarage $^2J_\ce{HH}$ is $\approx \pu{7 Hz}$ for a hydrocarbon with more than 2 carbons).
This particular spectrum consists of 90 peaks due to additional coupling of $\ce{P-^{15}N}$ coupling. If the compound is not labelled with $\ce{^{15}N}$, the number of peaks would reduced to 30 peaks, a relatively simplified spectrum, but still complicated coupling pattern of doublet of triplet of quintet.
