Three British coals and their iodine treated counterparts were examined in order to investigate the increase in electron paramagnetic resonance (e.p.r.) signal intensity that occurs upon iodine uptake. The iodine is not removed by vacuum. Scanning el

A bacterium identified as Arthrobacter sp. was grown on dibenzothiophene (DBT) sulfone as a sole source of sulfur, producing sulfite and sulfate. Sulfur in DBT sulfone (1.0 mM) was nearly quantitatively converted to sulfate by the organism. The organ

A coal-derived light distillate and a petroleum-derived residuum have been studied by high-resolution mass spectrometry using both low-pressure ammonia chemical ionization and low-voltage electron impact ionization. A mass calibration mixture for use

The oxidation state of copper in oxyhemocyanin is uncertain, since it does not display a copper(II) electron paramagnetic resonance signal unless the protein is denatured. We have utilized proton and phosphorus magnetic resonance line broadening tech
