The photoelectron spectrum of HCP and comments on the first photoelectron band of HCN

The photoelectron spectrum of HCP has been obtained, Ionization potentials are found at 10.79 ± 0.01 eV (X² Π) and 12.86 ± 0.01 eV (A ² Σ). By comparison with HCP, a new interpretation of the first photoelectron band of HCN has been proposed which involves a Renner-Teller interaction in the Σ⁺ vibronic states of the molecular ion.

Phosphorylation of Tetrahydric Phenols with Trivalent Phosphorus Compounds. Synthesis of Tetraphosphites

The reactions of 1,1'-spirobi(5,6-dihydroxy-3,3-dimethylindane) and 1,2,4,5-tetrahydroxybenzene with 2-chloro-1,2,3-dioxaphosphorinanes of various structure were used to obtain tetraphosphorylated systems. Investigation of the chemical properties of the products was initiated. Basing on 1,1'-spirobi(3,3-dimethylindane-5,6-diyl) tetra(2,2-dimethylpropanediyl phosphite), a Pt(II) chelate was synthesized.
