CO ( 4 – 3 ) and CO ( 3 – 2 ) studies of M 51 and NGC 6946
We have mapped several nearby galaxies in the CO(4–3) line transition with the Heinrich-Hertz-Telescope on Mt. Graham, Arizona, during an excellent weather period in December 1998. Here we report on our observations of M 51 and NGC 6946. The results suggest a concentration of highly excited CO gas to the nuclei of these galaxies. Moreover, in both objects CO(4–3) line emission was also detected...
متن کاملThe Crystallographic, Spectroscopic and Theoretical Studies on (E)-2-[((4-fluorophenyl)imino)methyl]-4-nitrophenol and (E)-2-[((3-fluorophenyl)imino)methyl]-4-nitrophenol Compounds
In this study, two new salicylideneaniline derivative compounds which are an isomer of each other have been synthesized and characterized by X-Ray Diffraction (XRD) technique, IR spectroscopy, and theoretical method. While (E)-4-(dihydroxyamino)-2-(((4-fluorophenyl)imino) methyl)phenol (1), crystalizes triclinic P-1 space group, (E)-4-(dihydroxyamino)-2-(((3-fluorophenyl)im...
متن کاملCrystal structure of [Co(NH3)6][Co(CO)4]2
Hexaamminecobalt(II) bis-[tetra-carbonyl-cobaltate(-I)], [Co(NH3)6][Co(CO)4]2, was synthesized by reaction of liquid ammonia with Co2(CO)8. The Co(II) atom is coordinated by six ammine ligands. The resulting polyhedron, the hexa-amminecobalt(II) cation, exhibits point group symmetry -3. The Co(-I) atom is coordinated by four carbonyl ligands, leading to a tetra-carbonyl-cobaltate(-I) anion in t...
متن کاملLow-temperature oxidation of CO catalysed by Co(3)O(4) nanorods.
Low-temperature oxidation of CO, perhaps the most extensively studied reaction in the history of heterogeneous catalysis, is becoming increasingly important in the context of cleaning air and lowering automotive emissions. Hopcalite catalysts (mixtures of manganese and copper oxides) were originally developed for purifying air in submarines, but they are not especially active at ambient tempera...
متن کاملTemporal changes in the emissions of CH 4 and CO from China estimated from CH 4 / CO 2 and CO / CO 2 correlations observed at Hateruma Island
In situ observation of the atmospheric CO2, CH4, and CO mixing ratios at Hateruma Island (HAT, 24.05 N, 123.80 E) often show synoptic-scale variations with correlative elevations during winter, associated with air transport from the East Asian countries. We examine winter (November–March) trends in 1CH4 /1CO2, 1CO /1CO2, and1CO /1CH4 observed at Hateruma over the period 1999 to 2010. To investi...
