Abstract

Electric dipoles are generated not only from the displacement polarization of nonpolar molecule and

the turning direction polarization of polar molecule but also from the collisions between atoms and molecules in

dense gas.The infrared photon is absorbed by molecule pairs formed in dense atmospheres of“cool”star and outer

planet due to the interactions between collision-induced dipole moments and electromagnetic radiation.The collision

  -induced absorption spectra are also introduced for hydrogen dense gas in white dwarfs atmospheres.
