High temperature absorption in the 10.4-mum band of CO(2)
Abstract:
The absorption coefficient of pure CO(2) has been measured as a function of temperature in the 295-650 K range for the P(14)-P(24) and R(10)-R(24) laser transitions. Cubic curves fitted to the experimental results are given to allow interpolation at all temperatures within the range. The P(20) transition shows an anomolously high value of absorption. Variation of absorption coefficient with pressure was linear but small for all transitions in the 200-700-Torr pressure range at three temperatures. Calculations of the absorption coefficient are performed and compared with experimental data.

Among the sp, sp2, and sp3 hybridized orbitals, sp orbitals have the maximum s character (50%). Consequently, the electrons are held more closely to the nucleus, resulting in stronger and shorter C–H bonds that stretch at a...
