Abstract:
New functional oligomers have been synthesized via intereaction of epoxy oligomers with carboxylic ones or with dibasic carboxy acids. In some cases synthesis was accompanied by ROP-polymerization of DGEBA, initiated by carboxylic oligomer. The structure of obtained products was investigated by IR, 1Н and 13C NMR spectroscopy.

Abstract:
This paper describes the synthesis and comprehensive characterization of tetrakis(pentafluoroethyl)germane. In addition to a complete NMR spectroscopic characterization, including the rarely used 73Ge NMR spectroscopy, Ge(C2F5)4 was studied by IR spectroscopy, mass spectrometry as well as X-ray diffraction analysis. A 73Ge NMR investigation as well as an X-ray diffraction study of the related germane Ge(CF3)4 are also included.

Abstract:
The (carbonyl)dihydride complex [(triphos)Ru(CO)H2] (2) has been synthesized by reaction of the ruthenate [(triphos)RuH3]K (triphos = MeC(CH2PPh2)3) with ethanol saturated with CO. A single crystal X-ray analysis and IR and NMR experiments have shown that 2 adopts in both the solid state and solution an octahedral coordination geometry with a facial triphos ligand, two cis terminal hydrides, and a terminal carbonyl. The reaction of hexafluoro-2-propanol (HFIP) with 2 has been studied in CH2Cl2 solution by IR and NMR spectroscopy. The proton donor interacts with a terminal hydride of 2 forming

The synthesis of trans-1.2-cyclohexanedioxydiacetamides starting with trans-1.2-cyclohexane-diol is described. Eleven of these compounds are characterized by IR, 1H NMR, 13C NMR and mass spectroscopy as well as elemental analyses. Most of these compounds are suitable ionophors for the cations K+ and Ca2+.

Abstract:
Correlations are presented for υasym.NCO vs. δ(13C) for NCO, δ13C for NCO vs. the number of protons on the alkyl α-carbon atom, and υasym.NCO vs. the number of protons on the alkyl α-carbon atom for alkyl isocyanates. Correlations such as these are useful in the elucidation of unknown molecular structures containing the isocyanate group.

Abstract:
A method has been developed to determine the exact fractional composition of binary mixtures of phospholipids at the air/water (A/W) interface by infrared spectroscopy in combination with 31P NMR spectroscopy and Langmuir-Blodgett surface chemistry. This procedure utilizes the wavenumber shift observed upon the synthetic replacement of hydrogen with deuterium in the lipid acyl chains to separate the vibrational bands due to each component in mixtures of deuterated and normally proteated lipids. Classical Langmuir-Blodgett monolayer transfer techniques are used to transfer the binary lipid mixt
