The relationship between orbital angular momentum and molecular chirality is conveniently introduced by reference to the methane structure which is stabilized by the anti-parallel alignment of two angular momentum vectors, figure 8. The balance is exactly symmetrical in point group Td:4¯3m only if...
showed increase in CH4 yield from CO2 by 13 times from 0.125 to 1.63 μmol/gcat h under solar light with methane selectivity improved from 25.7% to 85.8% by fluorination of TiO2 − x (53). The F atoms aid in improving the reduction potential of TiO2 − x by being substituted into ...
摘要: The possibility of defining the nonrigid motions of a molecule by improper elements of its point group is considered. The proposed method is presented for the example of the inversional motion of the methane molecule CH 4 in its ground electronic state....

than any of the satellites tested. These aircraft, which also surveyed the surrounding area in the course of data collection, did not detect any methane sources outside our test site. This strongly suggests that our results are free of interference from any significant confounding methane sources....
This category refers to a group of resources that contain hydrocarbons. The group ranges from volatile materials like methane, to liquid petrol, to non-volatile materials like anthracite coal [55]. Moreover, the agricultural land occupation category is the second highest category, having an impact...
