Nerf, R.B., Jr., 1975: Pressure broadening of the J = 1←0 transition of hydrogen cyanide. J. Molec. Spectrosc., 58, 479-480, doi:10.1016/0022-2852(75)90227-1.
Pressure broadening of microwave spectral lines is a useful source of information about rotational excitation of molecules by collisions. Such studies have been given added impetus in recent years by efforts to understand the formation of spectral Jines by interstellar molecules. Hydrogen cyanide (HCN) is of particular astrophysical interest because it is widely distributed in the interstellar medium and has a strong millimeter-wave spectrum. Laboratory broadening measurements of HCN are not possible at temperatures characteristic of interstellar clouds (<100 K) because of insufficient vapor pressure; the lowest practical temperature appears to be about that of dry ice (195 K). Broadening of the J = 1←0 line was observed at dry ice and room temperature (294 K); in addition to self-broadening, the effects of hydrogen (H2), deuterium (D2), and helium (He) were measured.
