The self‐broadening of the Q ‐branch vibration‐rotational lines in the CARS spectrum of HCl was studied over the pressure range 0.002‐1.000 bar and the temperature range 298‐1048 K. The broadening coefficients, σ p , are dependent on J at 298 and 550 K but are independent of J at higher temperatures; the σ p value of 1048 K is only about 25% of its value for J max at 298 K.
