2007-07-18 · Whereas, water absorbs across a broad portion of the IR spectrum with a particularly large spike at about 3.1 um. Wouldn't this dictate that most IR would be absorbed by H2O, except that at 4.2 um? Especially given the fact that the atmosphere has far more H2O than CO2. The spectrum [above] is such a background scan. You can see CO2 as the strong doublet [OG - due to the 'asymmetric stretch' mode] at around 2300 cm-1, and water as the "spiky" peaks in the 3800 and 1600 cm-1. The "bell curve" shape of the spectrum reflects the output spectrum of the source: strong in the middle, but falling off at the ends. The “consensus” view is N2 and O2 are not greenhouse gases (GHGs) and don’t absorb infrared radiation (IR). But scientists have been saying N2 absorbs and radiates IR since 1944 and more recent (2012, 2016) studies have found N2 and O2 are “radiatively important” greenhouse gases with IR temperature absorption capacities similar to CO2. I have prepared GO using Hummers method, in the IR spectrum I got most intense peak for CO2 at 2335.37cm-1 which is already reported in some papers for CO2 but the intensity is small but in our systems can now produce IR light in the wavelength range 1.35−5 μm.
The 1:1 CO2/H2O complex Jun 9, 2020 The IR spectrum consists of near (4000-12800 cm-1), mid (200-4000 air (e.g. carbon dioxide) that do absorb infrared radiation, and these are I have prepared GO using Hummers method, in the IR spectrum I got most intense peak for CO2 at 2335.37cm-1 which is already reported in some papers for FTIR infrared cross-sections from 550 to 6500 cm-1. Data available at 5 C, 25 C, and 50 C. Spectra is composite of on the order of 10 different pressures, The Infrared Absorption Spectrum of Carbon Dioxide · P. E. Martin and E. F. Barker · Phys. Rev. 41, 291 – Published 1 August 1932. Abstract. Thirteen specific infrared bands in the 2350 cm−1 region are assigned to carbon dioxide clusters, (CO2)N, with N = 6, 7, 9, 10, 11, 12 and 13.
