Abstract

The near-infrared absorption spectrum of He₂ has been recorded in the range of 12 090-13 300 cm^-1 using the optical heterodyne concentration modulation spectroscopy. Fifty-nine He₂ spectral lines were assigned to the (1, 0), (2, 0), (3, 1) and (4, 2) bands in the c³Σ_g⁺-a³Σ_u⁺ system and a non-linear least-squares fitting was performed to get the improved molecular constants for the levels (υ = 1, 3 and 4) in the upper electronic state.
