Temperature dependences of self- and N2-broadened line-shape parameters in the ν3 and ν5 bands of 12CH3D: Measurements and calculations

The j and k dependencies of the line coupling and line mixing effects: Theoretical studies of the relaxation matrices of N2-broadened CH3D

“…However, the situation is not clear in the ν 3 band: no line mixing effects have been obtained from the fittings by Malathy et al [3] . On the opposite, weak line mixing effects have been observed by Predoi-Cross et al [5] for some doublets in the QP(j,3) and QR(j,3) sub-branches. Their observed intra-doublet's matrix elements are listed in Table 1 .…”

“…The theoretical results consist of calculated halfwidths without LC (i.e., MRB), with LC (i.e., RRB), and with LM (i.e., RRB + LM). The measurements are by Predoi-Cross et al [5] and by Malathy et al [3] . As shown in Fig.…”

“…Therefore, in order to analyze the j and k dependencies of LC and LM, one needs to focus on these two factors. For the intra-doublet's off-diagonal elements of S 2 , the expression for CSF is simplified as (5) where W ( j i j f j i j f , 1 L 1 ) is the Wigner 6j symbol and D P matrix is defined in Eq. A(3) of Ref.…”

“…[1] and references therein). This is the reason why numerous studies have been devoted both experimentally and theoretically to the halfwidths (HWHM) and shifts of air-as well as self-broadened lines in various vibrational bands (a complete review can be found in [2][3][4][5] ).…”

Semi-classical calculations of self-broadening coefficients of OCS and HCN at temperatures between 200K and 298K

“…This model can be a suitable alternative to calculate pressure broadening coefficients and to study their temperature dependences. Indeed, this version of the RB formalism was applied with success to many collisional systems such as CH 3 D-CH 3 D [13], CH 3 D-N 2 [13] and CH3Cl-air [14] at various temperatures.…”
