The pressure‐broadening coefficients for the self‐broadened S 0 (0), S 0 (1) and S 0 (2) pure rotational Raman lines of hydrogen and the S 0 (0) to S 0 (4) lines of deuterium were determined experimentally over the pressure range 1–100 bar and the temperature range 90–375 K. Broadening coefficients were also determined for the same lines in hydrogen and deuterium perturbed by helium, argon, oxygen, nitrogen, carbon monoxide and hydrogen chloride over the pressure range 2–100 bar, with a partial pressure of the host gas of 1 bar and a temperature of 293 K. In addition, the S 0 (0) pure rotational line of deuterium broadened by carbon monoxide and nitrogen was studied over the same pressure range and a temperature range of 100–293 K. The results are discussed and compared with those of previous studies in the literature.
