The collisional broadening of infrared spectral lines of molecules is analyzed. It is shown that the indistinguishability of the particles leads to additional collisional transitions which are due to the exchange processes. This produces an additional broadening of spectral lines which correspond to optical transitions from the electronic-vibrational ground state. © 1995 American Institute of Physics.
