The Reaction Kinetics of Amino Radicals with Sulfur Dioxide

Abstract: Application of the laser photolysis–laser-induced fluorescence method to the reaction NH2 + SO2 in argon bath gas yields pressure-dependent, third-order kinetics which may be summarized as 𝑘 = (1.49 ± 0.15) × 10^−31 (𝑇/298 K) − 0.83 cm^6 molecule^−2 s^−1 over 292 – 555 K, where the uncertainty is the 95% confidence interval and includes possible systematic errors.The quenching of vibrationally excited NH2 is consistent with a high-pressure limit for NH2 + SO2 of (1.62 ± 0.25) × 10^−11 cm^3 molecule^−1 s^−1 over the temperature range 295–505 K, where again the 95% confidence interval is shown. Abinitio analysis yields a H2N – SO2 dissociation enthalpy of 73.5 kJmol−1, and comparison with RRKM theory and the exponential down model for energy transfer yields ⟨Δ𝐸⟩down = 350 cm^−1 for Ar at room temperature.

Examining Scientific Literacy through New Media (open access)

Examining Scientific Literacy through New Media

Article evaluates the impact of new media on scientific literacy. Content analysis with a coding scheme was performed on 42 filtered websites and 20 microblogs to analyze the role of new media in disseminating scientific knowledge. The results showed that the quality of science-oriented websites was higher than that of microblogs. Suggestions about how to improve the quality of science-oriented new media and how to develop students’ scientific literacy through new media are also discussed.

Solving the (n² - 1)-Puzzle with 8/3 n³ Expected Moves (open access)

Solving the (n² - 1)-Puzzle with 8/3 n³ Expected Moves

In this article, it is shown that the greedy algorithm for the (n² - 1)-puzzle makes 8/3 + O(n²) expected moves. This analysis is verified experimentally on 10,000 random instances each of the (n² - 1)-puzzle for 4 ≤ n ≤ 200.
