An extensive collection of IR spectra is available from the following National Institute of Standards and Technology (NIST) web site: http://webbook.nist.gov (Stein, 2003). Figures 2.23 and 2.24 depict the absorption spectra from the NIST database for CO 2 and CO respectively.
WebFeb 8, 2024 · The greenhouse gases in the dry air in Earth’s atmosphere include carbon dioxide, methane, nitrous oxide, ozone, and chlorofluorocarbons. While making up around 0.05% of Earth’s total atmosphere, they play major roles in trapping Earth’s radiant heat from the Sun and keeping it from escaping into space. Each is driven directly by human activities. WebNov 4, 2014 · An ir active band will be observed if a vibration results in a change of the dipole moment.
