“…Of interest to atmospheric physics is the broadening and shifting of the fundamental of CO perturbed by N 2 . Here the shifts are very small and it is not surprising that meaningful measurements of the shifts have only been made in the last few years using laser diodes (11,14,17,18), difference-frequency spectrometers (15,16), or high-resolution Fourier transform spectrometers (10,12,14). Even with these advanced instruments, the reported error bars often reach 100% and there is some disagreement between various authors.…”

“…The data on CO linebroadening and shifting coefficients are included in the spectroscopic database HITRAN. Numerous studies were made for the line shape parameters of CO in mixtures with various atmospheric gases (see Refs [200][201][202][203][204][205][206][207][208][209][210][211][212][213][214][215][216][217]. The fundamental band line shapes of CO-N 2 were experimentally studied in Refs [200][201][202].…”

“…Experimental line-broadening and line-shifting coefficients in the (1-0) and (2-0) bands [209,210] as well as the broadening coefficient of the rotational line J = 1 ← 0 [211] of self-perturbed CO were also obtained. The case of hydrogen-broadening was considered in Refs [201,[209][210][212][213]. The perturbation by CO 2 was analysed in Refs [201,214].…”

Water vapour is one of the strongest absorbers of radiation in the Earth's atmosphere, but some other gases also play an important role in the atmospheric radiative transfer processes: carbon dioxide CO 2 , carbon monoxide CO, ozone О 3 , methane CH 4 . Minor atmospheric pollutants such as hydrogen sulphide H 2 S, methyl fluoride CH 3 F, methyl chloride CH 3 Cl, ethylene C 2 H 4 , nitric oxide NO, nitrous oxide N 2 O and nitrogen dioxide NO 2 are equally recognised for their implication in the fundamental chemical reactions occurring in the terrestrial atmosphere. As a consequence, a lot of spectroscopic studies are made for these molecules in order to obtain the line positions, intensities and widths. They are briefly summarised below, starting by asymmetric waterlike molecules of X 2 Y-type which have the same selection rules for vibrotational spectra. Vibrotational lines of asymmetric X 2 Y moleculesBetween asymmetric tops of the X 2 Y type most attention in the spectroscopic literature is paid to the H 2 S, SO 2 , O 3 and NO 2 molecules. _________________________________________________________________ A vibrotational state (v 1 v 2 v 3 ) [J K a K c ] of these molecules is characterised by three vibrational quantum numbers v 1 , v 2 , v 3 and three rotational quantum numbers J, K a , K c . In the NO 2 molecule, having an unpaired electron (total electronic spin S = 1/2), each vibrotational level is split by the spin-rotational interaction into two components (J = N ± S) denoted by + or -, and the three rotational quantum numbers are N, K a , K c . For a given set of vibrotational quantum numbers the corresponding energies are obtained by a diagonalization of the effective Hamiltonian matrix of Eq. (3.

“…(14,15,17). A passive stabilization method as described by Sumpf et al (18) and Waschull et al (19) was used to reach a resolution of about 5 ⅐ 10 Ϫ4 cm Ϫ1 and due to the accumulation of about 30 pulses under identical experimental conditions, a sensitivity of about 10 Ϫ3 was achieved.…”
