We use the model of the overlap-induced, irreducible, ternary dipole (OITD) component of three interacting H[sub 2] molecules [Phys. Rev. A [bold 49], 4508 (1994)] to calculate the intensity of the triple [ital Q][sub 1] transition, observed by Reddy, Xiang, and Vaghese [following Letter, Phys. Rev. Lett. [bold 74], 367 (1995)] in compressed hydrogen gas in absorption near 12 466 cm[sup --1]. Such simultaneous transitions in three interacting molecules are thought to arise from irreducible, ternary dipole components. The calculated intensities agree with the measurement within a factor of 2 or 3, which shows once more that the OITD model is capable of describing ternary spectroscopic interaction in remarkable detail.
