Band strength and line half-width of the 10·4 μ CO2 band

Abstract

Ahatraet-Experimental absorption data using a 10.4 p COz laser have been re-analysed. The band intensity of the 10.4~ (lO%OO"l) CO, band is 0.0184 cm-' (atm cm2,30K)-1 f 5 y0 at 300°K and the self broadened Lorentz half-width of the P(20) tine is @096 cm-' f 5 % at 1 atm and 300°K.

A study of infrared radiation of vibrationally excited CO in the 4.7 μm band and CO2 in the 4.3 μm and 2.7 μm bands

“…The direct measurements of the collisional halfwidths of the rotational CO2 and CO band lines have been carried out by the authors of references [33][34][35] and [36,37], respectively. With particular reference to the CO2 molecule a slight difference has been detected between the collisional halfwidths of different vibrational transitions [33].…”

“…The calculation performed have been useful in finding out that the resultant maximum errors in the determination of the radiation intensity at the lowest rotational temperatures around Trot = 100 K do not exceed 5-10 %. [33][34][35][36][37][40][41][42]].…”
