Rotational spectroscopy - Wikipedia

Rotational spectroscopy has primarily been used to investigate fundamental aspects of molecular physics. It is a uniquely precise tool for the determination of molecular structure in gas phase molecules. It can be used to establish barriers to internal rotation such as that associated with the rotation of the CH 3 group relative to the C 6 HGet price

Quantification of the Sulfr hexafluoride lifetime based on mesospheric loss

The profiles of Γ sf 6 and Γ CO2 (Figure 2) show similar values in the lower stratosphere and relatively older SF 6 mean ages with increasing height. The nearly constant CO 2 mean ages of 5–6 years above 20 km are consistent with what we expect from many previous measurement‐based estimates of mean age in the midlatitude and high latitudeGet price
