P-31 NMR data of a 1,4-diphosphafulvene (alkylidene-2,3-dihydro-1H-1,3-diphosphole) and a 3,4-dihydro-1,3,4-triphosphacyclopenta[a]indene, bearing two or three chemically inequivalent phosphorus nuclei, were promising to be applicable for solution P-31 NMR quantum information processing, and demonstrations including implementation of the Deutsch-Jozsa algorithm with P-31 nuclei were examined.
