Methane resonance
Webwe report here the 13C n.m.r. chemical shifts of methane, ethane, propane, ethene, and propene in the gas phase at ca. 0.5 atm. Results are given in the Table. The results indicate that the solvent effects on methane must have been rather large; in the previous worklb the methane resonance was 45-6 p.p.m. upfield from (CD,),SO. WebThe Moon is Earth's only natural satellite.It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical …

WebMethane doesn't illustrate the difference very well, but the difference is nicely illustrated with benzene. Valence bond theory would have the electrons in the "double bonds" isolated between atoms as so: But the electrons in the "double bonds" are not isolated in three double bonds but distributed equally over all 6 carbon atoms.

WebObservations of third- and higher-order resonances in the absorption spectra of methane (resonance wavelength, 3.39 microns) are reported. Two methods for isolating third-order resonances are discussed. One method is based on a sinusoidal modulation of the lasing power by changing the discharge current in the amplifying element. This method can be …
