4.d.ii. Band paremeters of CO2
|
The number of narrow band and its band width are similar to those of
Savijärvi (1991a).
The line strength  and the square root of the
product of line strength and line width  are quoted from
those at 220 K listed by Houghton
(1986).
These values are listed in the following tables.
CO2 15 μm band ranges from 500
cm-1 to 900
cm-1 and 4.3 μm band ranges from
2200 cm-1 to 2450
cm-1, where  is equal to 25
cm-1.
CO2 2.7 μm band ranges from 3150
cm-1 to 4100
cm-1 and 4.0 μm band ranges from
4600 cm-1 to 5400
cm-1, where is equal to 100
cm-1.
