    Phosphorescence spectra of nonphosphorescent or very weakly phosphorescent new UV absorbers, 2-methylphenyl cinnamate (MePC), 2-methylphenyl 4-methoxycinnamate (MePMC) and 2-methylphenyl 4-ethoxycinnamate (MePEC) have been observed by using external heavy atom effects of ethyl iodide in ethanol at 77 K. The lowest excited triplet (T 1) energies of these new UV absorbers are lower than Cited by: Iodomethane, also called methyl iodide, and commonly abbreviated "MeI", is the chemical compound with the formula CH3I. It is a dense, colorless, volatile liquid. In terms of chemical structure, it is related to methane by replacement of one hydrogen atom by an atom of iodine. It is naturally emitted by rice plantations in small amounts. It is also produced in vast quantities estimated to be greater than Chemical formula: CH₃I.

The photophysical and photochemical properties of p-substitued 2-styryl-ethylbenzothiazolium iodides, possessing different electron-withdrawing or electron-donating groups are described. The dyes were prepared by the condensation of 3-ethylmethylbenzothiazole salts with p-substituted benzaldehydes. The synthesis of suitable substrates is.

Perdeuterated ethyl iodide in solid parahydrogen is photolyzed at K to find the formation of all deuterated ethylene, ethane, and ethyl radical and deuterium iodide.

The temporal change in the intensity of the vibrational spectra upon UV irradiation reveals that the initial ethyl iodide exists in both monomeric and dimeric units. The photolysis of ethyl iodide in solid parahydrogen leads to the formation of ethyl radical, ethylene, and ethane upon near-UV illumination at about 5 K which are characterized by vibrational spectroscopy.

The mechanism of the formation of the products is elucidated by: Radiation of wavelengths longer than nm produces ethyl hypoiodide, hydrogen hypoiodide, and ethanal. Subsequent Pyrex-filtered photolysis increases the yield of ethanal.

After quartz-filtered photolysis, hydrogen iodide is formed and the yield of ethanal by: Besides the ethyl iodide exhaled during treatment, additional amounts were exhaled after treatment. To study this latter factor the following method was used. Ethyl iodide was administered according to the procedure described above except that the outlet tube F (fig.

1) was led to the air outside the laboratory to prevent reinhalation of the ethyl iodide exhaled during the treatment. AsFile Size: 1MB. Gas‐Phase Photolysis of Ethyl Iodide at and Å. Reactions of Hot Ethyl Radicals with Added Hydrocarbons.

These data indicate that an exposure of L is sufficient to saturate the monolayer. We observe ethylene desorption at K during b-hydride elimination of ethyl groups on the Cu() surface.

This is identical to the temperature reported in a previous study of ethyl iodide decomposition on the Cu() surface [11]. The photo-induced trans/cis isomerization is one of the most important fundamental processes in photochemical and photo-biological reactions.
