✦ Synopsis

The He (Ia) photoelectron (PE.) spectra of a series of substituted 1,2-dithietes have been recorded and assigned with respect to the orbital sequence derived from an STO-3G model calculation and by correlation with the PE. spectra of related compounds. The results provide additional support for the presence of a closed, four-membered ring moiety in all the 1,2-dithietes investigated. In all cases the two highest occupied molecular orbitals are b2 ( n ) = HOMO, a2 (n), with exception of 3,4-bis (trifluoromethyl)-l,2-dithiete where the sequence b2 (n), a2 (n) or a2 (z), b2 ( n ) is uncertain.

The He(1a) PE and the electronic absorption spectra of hexafluorocyclobutanone (3) and tetrafluoro-I ,2-cyclobutanedione (4) have been recorded. The assignment of the observed bands in both types of spectra is mainly based on the correlation with the corresponding spectra of the parent compounds cyc

Osteogenesis imperfecta (OI) is a congenital disease of connective tissue, most often caused by single amino acid substitutions of glycine residues within the triple helical region of collagen I. Collagen I consists of two alpha 1 chains and one alpha 2 chain. Thus, a substitution in the alpha 1(I)
