Collision induced absorption in CO2 at 0.091 cm-1

Collision induced absorption in CO2 at 0.091 cm-1

2014 Collision induced microwave absorption has been studied at 0.091 cm-1 and 293 K up to 60 amagat density. Expressing the dielectric loss 03B5" in the form 03B5" = A03BD03C12(1 Bp), where 03BD is the frequency in cm-1 and p is the density, we find A = 0.22 10-7 (cm.amagat-2) and B = 0.008 2 (amagat-1). As a result the molecular quadrupole moment of CO2 is calculated to be 5.6 10-26 (esu). J....

Infrared collision-induced and far-line absorption in dense CO2 atmospheres

Wordsw Collision-induced absorption is of great importance to the overall radiative budget in dense CO2-rich atmospheres, but its representation in climate models remains uncertain, mainly due to a lack of accurate experimental and theoretical data....

Variable 21 cm absorption at z = 0 . 3127

We report multi-epoch GMRT HI observations of the z = 0.3127 damped absorber towards the quasar PKS 1127-145 , which reveal variability in both the absorption profile and the flux of the background source, over a timescale of a few days. The observed variations cannot be explained by simple inter-stellar scintillation (ISS) models where there are only one or two scintillating components and all...

Diode laser absorption spectrum of cold bands of C 2 HD at 6500 cm 1

The absorption spectrum of acetylene-d has been observed at high resolution between 6470 and 6630 cm 1 using an external cavity diode laser. Three cold bands have been observed: the strong 2m1 band, the weaker m1 + m2 + 2m5 band, and the (m1 + m3 + m5) 1 band, which gains its intensity through Coriolis resonance with 2m1. Centers of unblended lines are determined with an accuracy of approximate...
