The homonuclear and heteronuclear indirect spin-spin interactions in InP semiconductors have been studied using 31P cross polarization (CP) NMR spectra under magic-angle spinning (MAS). The isotropic contributions of the electron-coupled nuclear coupling between next-nearest neighboring 31P-31P spins and the nearest neighboring 113, 115In-31P spins were obtained as $|^2 J({^{31}}\text{P}, {^{31}}\text{P})| = 13\pm 5$ Hz and $|{^1 J}({^{113, 115}}\text{In}, {^{31}}\text{P})| = 224\pm 5$ Hz, respectively, for undoped and Fe-doped InP. We find no dependence of these $^{1, 2}J$ values on the carrier density in the range of $10^{7}$-$10^{15}$ cm- 3.
