Ultraviolet photodissociation of OCS: product energy and angular distributions.
The ultraviolet photodissociation of carbonyl sulfide (OCS) was studied using three-dimensional potential energy surfaces and both quantum mechanical dynamics calculations and classical trajectory calculations including surface hopping. The transition dipole moment functions used in an earlier study [J. A. Schmidt, M. S. Johnson, G. C. McBane, and R. Schinke, J. Chem. Phys. 137, 054313 (2012)] ...
متن کاملThe Ultraviolet - Far Infrared Energy Budget of the Gravitationally Lensed
A 2-hour service-mode SCUBA observation of the gravitationally-lensed Lyman break galaxy MS 1512–cB58 resulted in a 3σ upper limit of 3.9 mJy at 850μm. A comparison of this upper limit with values expected from rest-UV/optical measurements of extiction suggests that dust temperature (Td) and/or emissivity index (β) in cB58 may be substantially higher than is seen in local galaxies, or that the ...
متن کاملInhibition of pathogens on fresh produce by ultraviolet energy.
Ultraviolet energy at a wavelength of 253.7 nm (UVC) was investigated for its bactericidal effects on the surface of Red Delicious apples, leaf lettuce and tomatoes inoculated with cultures of Salmonella spp. or Escherichia coli O157:H7. Inoculated samples were subjected to different doses ranging from 1.5 to 24 mW/cm(2) of UVC and enumerated on tryptic soy agar plus 0.05 g/l nalidixic acid to ...
متن کاملDust and the Ultraviolet Energy Distribution of Quasars
The ultraviolet energy distribution of quasars shows a sharp steepening of the continuum shortward of 1000 Å (rest-frame). We describe how we came to consider the possibility that this continuum break might be the result of absorption by carbon crystallite dust grains.
متن کاملClostridium difficile Spore Inactivation Study Using Ultraviolet-C Energy
METHOD: This study was carried out in a controlled laboratory environment setting. Clostridium difficile spores were placed in a laboratory room, in direct line of sight of the UV-C emitter device (the Emitter). This study only used definitive, preselected UV-C dose settings and was not based on treatment time or the distance the coupons were located from the Emitter. The dose delivered was mea...
