. The kinetics of the absorption of carbon monoxide by basic solutions was studied at 80°C and carbon monoxide pressures up to 30 atmospheres. The reaction was followed by the rate of decrease of carbon monoxide pressure in a closed system. The observed kinetics in potassium hydroxide solutions yield a rate law of the form (formula omitted) No influence from Li⁺, Na⁺, K⁺ ions was detected and no catalytic effect from Ag(I),- Cu(II), T1(I), N0₃⁻, Mn0₄⁻ was observed. The kinetics are consistent with a mechanism which includes the insertion of a carbon monoxide molecule into the hydroxyl bond,viz. (formula omitted) The rate-controlling step above 90°C was found to be the mass transfer of carbon monoxide from the gas phase into the liquid phase under the conditions involved in this study. / Applied Science, Faculty of / Materials Engineering, Department of / Graduate

When deoxybenzoin oxime was reacted with carbon monoxide and hydrogen in the presence of dicobalt ootacarbonyl at elevated temperatures and pressures 3-benzylphthalimidine and 3-phenyl-3,4-dihydroisocarbostyryl were produced. When 2-acetonaphthone oxime was reacted under similar conditions 2-(β-naphthyl)-4-methyl-benzo[h] quinoline, 3-methylbenzo[f]phthalimidine and 1- (β-naphthyl)ethylurea were produced. Verification of the structure of 2-(β-naphthyl)-4-methylbenzo[h]-quinoline was attained in part through the hydrochloride salt, the methiodide salt, the picrate derivative and the 2-(β-naphthyl)-4-formylbenzof[h]-quinoline derivative. 2-(β-Naphthyl)-4-methyl-benzof[h] quinoline was also synthesized by reacting 2- acetonaphthone oxime with 2-acetonaphthone at elevated temperatures. The infrared spectra of the above compounds are described. / Science, Faculty of / Chemistry, Department of / Graduate

The electronic emission spectra of the CO molecule in an applied electric field of 53.8 kilovolts/cm has been observed. The electric field was determined from the Stark Effect on the H line at 4340Å. The spectra were produced in the high field region of a low pressure glow discharge using carbon monoxide gas and water vapour. The electric dipole moment of the CO molecule has been determined for the BlΣ+ state using the P(l) transition of the Ångstrom ( 0 , 0 ) band. The effect observed is a second order effect in the B1Σ+ state and it has been deduced that the dipole moment of the A1π state is very small or zero. The dipole moment of the B1Σ+ state is 1.61 debye ± 14%. / Science, Faculty of / Physics and Astronomy, Department of / Graduate

Gas giant exoplanets known as hot Jupiters orbit close to their parent stars and are heated to high temperatures. Their infrared spectra, measured by photometry during secondary eclipses, are dominated by carbon monoxide and methane, the principle reservoirs of carbon on these planets. The relative CO and CH4 abundances inform us about temperature and pressure conditions and also about mixing by global winds driven by intense but asymmetric heating for these tidally locked bodies. Emission spectra collected during secondary eclipses, as the hot Jupiter passes behind its parent star, in principle allows a determination of the CO:CH4 concentration ratio. Since hot Jupiters exist at temperatures of order 700 K, accurate model atmospheres require high temperature line lists for relevant molecules, for which existing data bases are apparently incomplete. Since the outer atmospheres of hot Jupiters are bombarded by intense ultraviolet radiation and energetic particles, there may even be a significant degree of ionization and nonequilibrium populations among the various molecular levels. Here we present high temperature emission spectra of CO obtained from a microwave discharge plasma, where the source of CO was carbon dioxide that dissociates under microwave heating. The spectrum was measured in the range 1800-2400 cm-1 at a resolution of 0.1 cm-1 . Vibrational transitions originating in up to the 13th vibrational level of the X 1  + ground electronic term were observed. From the J values for maximum intensity lines within the rotational fine structure, we obtain a temperature estimate of ~700 K, which is comparable to the atmospheric conditions of hot-Jupiters.
