Show affiliationsEnhancement spectra of the collision-induced absorption (CIA) of H2 in the region 5600–9500 cm−1 in binary H2–N2 mixtures were investigated at room temperature for base densities of H2 in the range 89–145 amagat and for partial densities of N2 in the range 30–350 amagat. Enhancement absorption profiles of H2–N2 in the investigated region consist of the superposition of two main parts, the first part is formed of quadrupolar double transitions of the type X1(J) + X1(J) in the range 5600–8500 cm−1 and the second formed of quadrupolar single transitions of the type X2(J) + X0(J) from 7500 to 9500 cm−1, where X is an O(ΔJ = −2), Q(ΔJ = 0) or S(ΔJ = +2) transition. The Birnbaum–Cohen lineshape function was found to give satisfactory fits of the synthetic profiles to the experimental profiles. Lineshape function parameters obtained from the analysis are given.
