    To calculate absorption coefficient

    Hi. Thanks a lot for ur reply. I calculated the absorption cross section.Pls let me know if it right pls forget about that 1% just assume concentration is 8500ppm A = 0.32, P = 1 atm, R = 0.082 liter * (atm/mol) * * deg k length = 100cm, T = let say (294K ) --- assuming 21C...

    To calculate absorption coefficient

    HI Thanks for ur reply We assume only Acetylene is responsible for absorption.No need to worry about N2. expt details I used HOllow core Photonic crystal fiber(HC-PCF) as path length,NIR Laser diode(NIR-1531.6nm ) as light source and photo detector for detection of light. At 1531.6nm...

    To calculate absorption coefficient

    I want to calculate absorption cross-section by using Beer-Lamberts law for Acetylene gas at NIR region.I. The calibration done at 1531.6nm. Absorbance= log to base10(intensity of incident light/intensity after passing through gas cell) = 0.32 ;;;;gas cell filled with Acetylene gas...

    To calculate absorption coefficient

    want to calculate absorption coefficient or absorption crosssection for 1% C2H2 gas Path length = 1meter Absorbene = 0.32 concentration = 8500ppm pressure = 1 atm Temperature = 25C I need to express this concentration to mol/cm3. Pls let me know if u have anyidea
