How does the the Far IR absorption coefficient of CO2 gas change with increasing pressure. Does it increase ,decrease or does it remain unchanged?

At low and moderate pressures, CO2 molecules will collide with each other and the collisions will not change the absorption coefficient. But at very high pressures, CO2 molecules start interacting with each other then absorption coefficients could change.
