“…The DH f values adopted in the present study for n-alkyl iodide liquids with carbon numbers (n) ranging between 1 and 10 are listed in Table 6. These values are consistent with the experimental determination reported by Carson et al (1994) for liquid ethyl iodide and a methylene -CH 2 -group increment of -25.73 kJ mol À1 (Domalski and Hearing, 1993).…”

“…The values obtained by these authors for the liquids differ from the values recommended by Cox and Pilcher (1970) by 1.5 and 5.0 kJ mol À1 for methyl iodide and ethyl iodide, respectively. Carson et al (1993Carson et al ( , 1994 also report experimental values for the enthalpies of formation at 25°C and 1 bar of liquid diiodomethane (XII), 1,3-diiodopropane (XIV), and 1,4-diiodobutane (XV), as well as of crystalline triiodomethane (XVIII), tetraiodomethane (XIX), and 1,2-diiodoethane (XIII). Sabbah and Rojas Aguilar (1996) have redetermined the standard molal enthalpies of formation of crystalline 2-, 3-, and 4-iodobenzoic acids (XXXVI-XXXVIII) and obtained values significantly different from the previous recommended values of Cox and Pilcher (1970), which were calculated from standard molal enthalpies of combustion reported by Smith (1956).…”

We studied photoinduced reactions of diiodomethane (CH(2)I(2)) upon excitation at 268 nm in acetonitrile and hexane by subpicosecond-nanosecond transient absorption spectroscopy. The transient spectra involve two absorption bands centered at around 400 (intense) and 540 nm (weak). The transients probed over the range 340-740 nm show common time profiles consisting of a fast rise (<200 fs), a fast decay ( approximately 500 fs), and a slow rise. The two fast components were independent of solute concentration, whereas the slow rise became faster (7-50 ps) when the concentration in both solutions was increased. We assigned the fast components to the generation of a CH(2)I radical by direct dissociation of the photoexcited CH(2)I(2) and its disappearance by subsequent primary geminate recombination. The concentration-dependent slow rise produced the absorption bands centered at 400 and 540 nm. The former consists of different time-dependent bands at 385 and 430 nm. The band near 430 nm grew first and was assigned to a charge-transfer (CT) complex, CH(2)I(2) (delta+)I(delta-), formed by a photofragment I atom and the solute CH(2)I(2) molecule. The CT complex is followed by full electron transfer, which then develops the band of the ion pair CH(2)I(2) (+)I(-) at 385 nm on the picosecond timescale. On the nanosecond scale, I(3) (-) was generated after decay of the ion pair. The reaction scheme and kinetics were elucidated by the time-resolved absorption spectra and the reaction rate equations. We ascribed concentration-dependent dynamics to the CT-complex formation in pre-existing aggregates of CH(2)I(2) and analyzed how solutes are aggregated at a given bulk concentration by evaluating a relative local concentration. Whereas the local concentration in hexane monotonically increased as a function of the bulk concentration, that in acetonitrile gradually became saturated. The number of CH(2)I(2) molecules that can participate in CT-complex formation has an upper limit that depends on the size of aggregation or spatial restriction in the neighboring region of the initially photoexcited CH(2)I(2). Such conditions were achieved at lower concentrations in acetonitrile than in hexane.

Computational studies on the mechanism and kinetics of Cl reaction with C₂H₅I

The dual-level direct kinetics method has been used to investigate the multichannel reactions of C(2)H(5)I + Cl. Three hydrogen abstraction channels and one displacement process are found for the title reaction. The calculation indicates that the hydrogen abstraction from -CH(2)- group is the dominant reaction channel, and the displacement process may be negligible because of the high barrier. The rate constants for individual reaction channels are calculated by the improved canonical variational transition-state theory with small-curvature tunneling correction over the temperature range of 220-1500 K. Our results show that the tunneling correction plays an important role in the rate constant calculation in the low-temperature range. Agreement between the calculated and experimental data available is good. The Arrhenius expression k(T) = 2.33 x 10(-16) T(1.83) exp(-185.01/T) over a wide temperature range is obtained. Furthermore, the kinetic isotope effects for the reaction C(2)H(5)I + Cl are estimated so as to provide theoretical estimation for future laboratory investigation.
