The Photolysis of Methyl Iodide

Methyl iodide poisoning.

Accelerated degradation of methyl iodide by agrochemicals.

The fumigant methyl iodide (MeI, iodomethane) is considered a promising alternative to methyl bromide (MeBr) for soil-borne pest control in high-cash-value crops. However, the high vapor pressure of MeI results in emissions of a significant proportion of the applied mass into the ambient air, and this may lead to pollution of the environment. Integrating the application of certain agrochemicals...

Low-temperature dynamics of confined methyl iodide

The rotational tunneling and librational excitations of the one-dimensional quantum rotor, methyl iodide, confined in porous glass monoliths ~mean pore diameter of 58 Å! have been investigated using incoherent inelastic neutron scattering. When the pores are completely filled with the solid at low temperatures (5 K ,T,35 K), the system exhibits a tunneling spectrum composed of two sets of inela...

(E)-1-Methyl-2-styrylpyridinium iodide

In the title compound, C(14)H(14)N(+)·I(-), the cation exists in an E configuration with respect to the ethenyl bond and is slightly twisted, the inter-planar angle between the pyridinium and phenyl rings of the cation being 4.8 (2)°. In the crystal packing, the cations are stacked in an anti-parallel fashion along the a axis by a π-π inter-action involving both pyridinium and phenyl rings; the...

Methyl iodide production from marine phytoplankton cultures

Unialgal cultures of 15 species of marine phytoplankton were examined for the production of methyl iodide (CHJ). CH,I production was quantified during log and stationary phases of phytoplankton growth in f/2 medium and compared to CHJ levels in control vessels. Significant increases in CHJ production were seen in five cultures. Phytoplankton CHJ production varied from a low of lop4 amol CHJ cel...
