Diode laser kinetic spectroscopy of formyl
A tunable diode laser infrared high-resolution spectrometer was constructed to study the spectroscopy and kinetics of free radicals. A method for producing diode laser frequency scans which are several wavelengths long, ...
The use of infrared kinetic spectroscopy to study small free radicals
The technique of infrared kinetic spectroscopy has been used to study the reaction of the propargyl radical (C3H3) with nitric oxide (NO). The overall rate constant at the high pressure limit for the reaction was determined ...
Synthetic studies toward the total synthesis of (+)-anthramycin total syntheses of (+)-neothramycins A and B
Through the serendipitous discovery of a palladium catalyzed conversion of ethylthiol esters to their corresponding aldehydes, the pyrrolo (1,4) benzodiazepine systems found in (+)-anthramycin 1a* and (+)-neothramycins A ...
Synthesis, characterization and magnetic property studies of copper-based phosphate and silicate compounds containing nanosize transition metal oxide frameworks
The search for novel compounds with nanosize transition metal oxide frameworks is important for the study and understanding of materials with interesting and important magnetic and electronic properties. These low-dimensional ...
Synthetic studies towards the total synthesis of discorhabdin C
Two synthetic approaches towards the total synthesis of discorhabdin C (3) are described. The general strategy for construction of azacarbocyclic spiro dienone system is to employ an intramolecular para-phenolic alkylation ...
A study on methane emission from rice paddy fields and the nonstructural carbohydrates in rice plants
A dynamic process of the nonstructural carbohydrate translocation in rice plants is presented based on observation during one growing season. Differing amounts of nonstructural carbohydrates might be lost through rice ...
Use of endohedral metallofullerenes for nuclear medicine applications
The metallofullerenes, Hox C82 (x = 1,2) and Gd C 82 were generated, sublimed from carbon-arc soot, and further purified by HPLC. Sample purity was then judged by LD-TOF MS and compared with purities obtained by ICP-AE and ...
Compact gas sensors based on mid-infrared frequency conversion of semiconductor lasers
Design, development, and application of novel all-solid-state spectroscopic gas sensors is reported. These compact instruments employ mid-infrared difference-frequency generation pumped by room-temperature semiconductor ...
Transition metal-catalyzed hydroboration
Model studies on rhodium catalyzed hydroborations of sterically unbiased alkenes with catecholborane provided evidence for the role of d$\pi$-p$\pi$ bonding in these transformations. Catalyzed hydroborations of ...
