“…In recent years it has been shown that for some gasperturber systems, such as for example, foreign-gas broadened water, this scaling law is not always appropriate [31][32][33][34]. It will be shown below that the power-law model does not work reasonably well for the CO 2 -CO 2 system.…”

Using a Fourier transform spectrometer setup we have measured the self-broadened half width, pressure shift, and line asymmetry coefficients for transitions in the 30012'00001 and 30013'00001 vibrational bands of carbon dioxide for four different temperatures. A total of 46 pure CO 2 spectra were recorded at 0.008 and 0.009 cm À 1 resolution and at pressures varying from a few Torr to nearly an atmosphere. The individual spectral line profiles have been fitted by a Voigt profile and a speeddependent Voigt profile, to which we have added dispersion profiles to account for weak line mixing. A comparison of the sets of results obtained for each band showed no vibrational dependence of the broadening coefficients. The self-broadening and selfshift coefficients are compared to semiclassical calculations based on the RobertBonamy formalism and were found to be in good agreement. The line asymmetry results are compared to line mixing calculations based on the Energy Corrected Sudden (ECS) and Exponential Power Gap models.

“…The algorithm has been improved for the current release of HITRAN: additional measurements of γ air and δ [18,[33][34][35][36][37][38][39] and γ self [18,[38][39][40][41][42][43][44][45] have been added to the measurement databases. Additional data [46,47] have been added to the theoretical database of γ air , n, and δ. The database of calculations of γ self for water vapor now contains the data of Antony et al [48,49] and Cazzoli et al [44].…”

“…The temperature dependence of the air-broadened half-widths has now been added to all water-vapor transitions via an algorithm that first seeks values from CRB (Complex RobertBonamy) calculations [46,47,50]. If a CRB value for a transition is not found, the n values as a function of rotational quantum numbers from Table 7 of Ref.…”

“…air , δ air , and γ self were added using a rather sophisticated scheme explained in Ref [40]. that determines and eliminates the experimental outliers and then either uses their averages from the measurement databases[41], if they exist, or values from single measurements, or theoretical complex Robert-Bonamy values (see for instance Refs [42,43][44]…”

An accurate and complete empirical spectroscopic database is constructed for natural water in the 5850-8340 cm-1 near infrared region (1.71-1.20 μm). The global list includes more than 46500 transitions of the six most abundant isotopologues (H 2 16 O, H 2 18 O, H 2 17 O, HD 16 O, HD 17 O, HD 18 O) in natural isotopic abundance with intensity greater than 1×10-29 cm/molecule. All line positions were obtained by difference of empirically determined energy values. These empirical determinations are mostly based on extensive investigations of water spectra by high sensitivity CRDS complemented with literature data. In particular, the sets of energy levels of the minor isotopologues have been significantly enlarged from very recent analysis of CRDS spectra of D, 18 O and 17 O enriched water samples. The empirical line positions were associated to experimental intensity values from the literature obtained by FTS for the strong lines and CRDS for weaker lines. The list is made mostly complete by including a large number of weak transitions not yet detected, with empirical positions calculated from empirical levels associated with variational intensities. Air-and selfbroadening coefficients have been added to each transition using the most recent version of the algorithm used for the HITRAN and GEISA databases. Examples of comparison of CRDS spectra to simulations based on the HITRAN2012 list illustrate the advantages of our database. The relative merit of experimental and variational line intensities is discussed. A separate line list combining empirical line positions and variational intensities is provided. Future improvements from combination of experimental and variational intensities are suggested.
