Atmospheric Chemistry of Titan : Ab Initio Study of the Reaction between Nitrogen Atoms and Methyl Radicals
Ab initio calculations were performed on the reaction N + CH3 products. Optimized geometries have been calculated for all reactants, transition states, and products at the MP2/6-31G1* level. Barriers and heats of reaction have been estimated by fourth-order Mdler-Plesset perturbation theory with spin projection (PMP4(SDTQ)). Harmonic vibrational frequencies and zero-point energy corrections wer...
متن کاملAb initio pressure-dependent reaction kinetics of methyl propanoate radicals.
The unimolecular dissociation and isomerization kinetics of the three methyl propanoate (MP) radicals, CH3CH2C(=O)OĊH2 (MP-m), CH3ĊHC(=O)OCH3 (MP-α), and ĊH2CH2C(=O)OCH3 (MP-β), are theoretically investigated using high-level ab initio methods and the Rice-Ramsperger-Kassel-Marcus (RRKM)/master equation (ME) theory. Stationary-point energies are obtained using the coupled cluster singles and do...
متن کاملthe relationship between collocational competence and listening comprehension
پس از پیدایش روش تدریس tpr توسط جیمز اشر که توجه و تآکید بسیاری بر مهارت شنیداری داشت زبانشناسان همواره در صدد یافتن راههایی برای بهبود این مهارت در زبان آموزان می باشند. از طرفی جی-آر-فرث که از پیشگامان زبانشناسی می باشد بر تآثیر لغات و بویژه گروه کلمات که اغلب در گفتار با هم می آیند (هم آیی کلمات)تأکید بسیار کرده است. به این دلیل و به منظوربررسی رابطه بین این دو عامل یعنی درک شنیداری و دانش...
15 صفحه اولthe relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
15 صفحه اولthe relationship between critical thinking and reading strategies
during the process of reading, sometimes learners use ineffective and inefficient strategies and some factors may influence their use of strategies. perhaps critical thinking is one of these factors. this study aims to identify those categories of reading strategies that are mostly used by iranian efl learners and to see if there is any significant relationship between the critical thinking abi...
