The chemiluminescence of organic compounds in solution is briefly surveyed with some emphasis on the mechanisms which result in relatively efficient population of an excited state of a product molecule. This is done in terms of the relation = x 'E 1F with particular reference to peroxide compositions. iNTRODUCTION The study of chemiluminescence mechanism in a persistent and systematic fashion i...

C293 physico-chemical properties. NN414 is a very weak acid with pKa = 8.5, log P = 1.6, and molar weight Mw = 291.8 g/mol. Two true polymorphs, A and B, of this compound have been identified. Polymorph A crystallizes in needleshaped crystals with a triclinic unit cell by precipitation from a variety of solvents such as acetic acid, acetonitrile, diluted ammonia, methanol, N-methyl-pyrrolidone,...

The carbonaceous chondrite meteorites are fragments of asteroids that have remained relatively unprocessed since the formation of the solar system 4.6 billion years ago. These carbon-rich objects contain a variety of extraterrestrial organic molecules that constitute a record of chemical evolution prior to the origin of life. Compound classes include aliphatic hydrocarbons, aromatic hydrocarbon...

VOCs comprise both methane (CH 4) and non-methane volatile organic compounds (NMVOCs). NMVOCs are defined as " all those artificial organic compounds different from methane which can produce photochemical oxidants by reaction with nitrogen oxides in the presence of sunlight " .

BACKGROUND Although "uremic fetor" has long been felt to be diagnostic of renal failure, the compounds exhaled in uremia remain largely unknown so far. The present work investigates whether breath analysis by ion mobility spectrometry can be used for the identification of volatile organic compounds retained in uremia. METHODS Breath analysis was performed in 28 adults with an eGFR ≥ 60 ml/min...

An increasing interest in organic agriculture for food production is seen throughout the world and one key reason for this interest is the assumption that organic food consumption is beneficial to public health. The present paper focuses on the background of organic agriculture, important public health related compounds from crop food and variations in the amount of health related compounds in ...

To answer critical questions regarding the interactions between green plants and air quality, two three-year projects are underway to investigate emission of volatile organic compounds (VOC) from selected plant species. These biogenic VOC (BVOC) and oxides of nitrogen (NOx) can react in the lower atmosphere in the presence of sunlight to form ozone and secondary particulate matter, the principa...

X-ray crystallography is an important method for determination of the arrangement of atoms within a crystal of compound in which a beam of X-rays strikes a crystal and causes the beam of light to spread into many specific directions. From electron density, in the molecule the mean positions of the atoms in the crystal can be determined, as well as their chemical bonds and various other informat...
