Spectrophone Measurements in Sulfur Hexafluoride [PDF]

open access: yesIEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1986
The optoacoustic signal generated by pulsed 10.6 c infrared radiation incident upon a test cell filled with gaseous SF6 has been analyzed in detail. The effects ofm icroscopic energy transfer from the absorbing vibrational degrees of freedom, spontaneous emission, thermal conduction, and acoustic wave propagation are included.

Extremely Nonlinear Optics Using Shaped Pulses Spectrally Broadened in an Argon- or Sulfur Hexafluoride-Filled Hollow-Core Fiber

open access: yesApplied Sciences, 2015
In this contribution we present a comparison of the performance of spectrally broadened ultrashort pulses using a hollow-core fiber either filled with argon or sulfur hexafluoride (SF6) for demanding pulse-shaping experiments.

Nucleation of sulfur hexafluoride

open access: yesAIP Conference Proceedings, 2000
We measured the homogeneous nucleation of sulfur hexafluoride using a diffusion cloud chamber under conditions that avoid the possibility of non-diffusive modes of transport within the cloud chamber thus ensuring reliable data from our measurements. We extended the critical supersaturation measurements into the critical region for SF6 using helium as ...

Declining, seasonal-varying emissions of sulfur hexafluoride from the United States [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Sulfur hexafluoride (SF6) is the most potent greenhouse gas (GHG), and its atmospheric abundance, albeit small, has been increasing rapidly. Although SF6 is used to assess atmospheric transport modeling and its emissions influence the climate for ...
