Synthesis of tetrahydroisoquinoline with a 1,4-bridged 10-membered sulfur contg. macrolactone, I (R = CO2CH2CCl3), is described. Phenolic aldolization, Pictet-Spengler cyclization of an acid sensitive amino diol under newly developed conditions (LiBr, tolu ...
Calcns. of 13C nuclear shieldings for low-energy isomers of C36H2x (x = 2,3) suggest that it should be possible to use exptl. 13C shifts, when these become available, to distinguish the isomeric form of the underlying fullerene cage and, in the case of iso ...
The electroreduction of hydrogen on Pt(III) in acidic media is the primary fuel cell reaction. The explicit mechanism for this process involves a first order phase transition, which is due to the rotation of the water dipole as the electric field is change ...
We propose a new mechanism for the electroreduction of hydrogen in acidic media. The specific model and theoretical calculations are designed for the Pt(111) surface, because this is the only face that exhibits a clear first order phase transition. The bas ...
Monolayer adsorption of benzoic acid derivatives on activated oxide surfaces from solution and from the vapor phase are investigated with the view of modifying the work function of a conductive substrate. Para-substituted benzoic acids with a wide range of ...
In this work, new spectroscopic techniques have been developed to measure electric dipole moments of highly excited rovibrational states of small polyatomic molecules in the gas phase. These techniques make use of lasers arid of microwave synthesizers. The ...
An atomic-scale description is provided for the long-range oxygen migration through the disordered SiO2 oxide during silicon oxidation. First-principles calculations, classical molecular dynamics, and Monte Carlo simulations are used in sequence to span th ...
We describe a microwave-optical double resonance experiment designed for Stark effect measurements on molecules in excited vibrational energy levels of ground electronic states. This technique, which employs pulsed laser excitation and laser induced fluore ...
Meta(tetrahydroxyphenyl)chlorin (m-THPC) is a new photosensitizer currently undergoing clin. trials at Lausanne's CHUV hospital for photodynamic therapy (PDT) of early cancer in the upper aerodigestive tract. The illumination of m-THPC with light at 650 nm ...
