31P NMR has been done in the paramagnetic state of SmCoPO. Hisohf, Haxhf are 13.4 and -5.19 kOe/$\mu$B respectively have been estimated which indicates the nature of hybridization between P 2p orbitals with Co 3d orbitals. Anisotropic spin-lattice relaxation rate has been observed. In plane spin-correlations are 2D FM and out of plane spin correlations are AFM type. {\textcopyright} 2012 American Institute of Physics.
