Measurements and modelling of molecular iodine emissions, transport and photodestruction in the coastal region around Roscoff
molecular iodine photodestruction the coastal region around Roscoff
<
2010/12/28
Iodine emissions from the dominant six macroalgal species in the coastal regions around Roscoff, France, have been modelled to support the Reactive Halogens in the Marine Boundary Layer Experiment (RH...
Spectroscopic studies of molecular iodine emitted into the gas phase by seaweed

<
2010/8/16
Time profiles of molecular iodine emissions from seven species of seaweed have been measured at high time resolution (7.5 s) by direct spectroscopic quantification of the gas phase I2 using broadband ...
In situ measurements of molecular iodine in the marine boundary layer: the link to macroalgae and the implications for O3, IO, OIO and NOx
molecular iodine the marine boundary layer macroalgae the implications for O3, IO, OIO and NOx

2009/3/13
We present the first in situ detection of molecular iodine emitted from the brown macroalga Laminaria digitata under natural stress conditions. We show that the release of I2 occurs in short, strong b...

Renewal of ultrafine aerosols in the marine boundary layer may lead to repopulation of the marine distribution and ultimately determine the concentration of cloud condensation nuclei (CCN). Thus the f...
Modelling molecular iodine emissions in a coastal marine environment: the link to new particle formation

2009/1/5
A model of iodine chemistry in the marine boundary layer (MBL) has been used to investigate the impact of daytime coastal emissions of molecular iodine (I2). The model contains a full treatment of gas...
Direct Iodination of Aromatic Compounds with Polyvinylpyrrolidone Supported Hydrogen Peroxide (PVP-H2O2) and Potassium Iodide or Molecular Iodine
iodinated aromatic compounds iodination hydrogen peroxide supported reagents
<
2007/12/19
摘要 Hydrogen peroxide was supported on polyvinylpyrrolidone to afford a stable and mild oxidizing reagent. Activated aromatic compounds were reacted with PVP-H2O2 in the presence of KI or I2 and a cata...
Chirped pulse enhancement of multiphoton absorption in molecular iodine

<
2014/9/24
Chirp effects on three photon absorption yields in I2 vapor are investigated using femtosecond pulses with center wavelengths in the region 550–600 nm. Enhancements of as much as a factor of 3 are obs...
