WebKerogen is solid, insoluble organic matter in sedimentary rocks. Comprising an estimated 10 16 tons of carbon, it is the most abundant source of organic compounds on earth, exceeding the total organic content of living matter 10,000-fold. [1] It is insoluble in normal organic solvents and it does not have a specific chemical formula. WebThe electronic ground state and first excited state (Ã 2 Σ +) of phosphaethyne cation (HCP +) have been systematically investigated using ab initio electronic structure theory. The total energies, geometries, rotational constants, dipole moments, harmonic vibrational frequencies, and parameters for Renner–Teller splittings were determined using self …

This suggests that the thermodynamically controlled product is the 1,3,5-triphosphinine, while 1,3,6-triphosphafulvene is the kinetically favored product. For the latter a biradical reaction pathway also exists. grants for opening child care facility
