Absorption Spectrum 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...

Localizing of a Four-Level Atom via Absorption Spectrum

We propose a scheme for localizing an atom in a four-level configuration inside a classical standing wave field, conditioned upon the measurement of frequency of a weak probe field. In the classical standing wave field, the interaction between the atom and the field is position dependent due to the Rabi-frequency of the driving field. Hence, as the absorption frequency of the probe field is mea...

Controlling of Absorption and Dispersion Spectrum via Electromagnetically Induced Transparency

In this paper we examine the absorption and dispersion properties of a weak probe field via Electromagnetically Induced Transparency (EIT) in a four-level system. It is shown that under certain condition, using this model, the absorption cancellation is appeared and the medium becomes transparent to the weak probe field. It will be shown that the controlling of absorption and dispersion spectru...
