Popis:	High‐dispersion measurements have been made for the first time on the fundamental, first overtone, and second overtone infrared vibrational bands of DBr. Path lengths from 40 cm to 17 m were used with pressures ranging from 90 mm to 460 mm. The isotopic splitting of the rotation lines was measured and molecular constants determined for both isotopic species, DBr79 and DBr81. The principal constants for DBr79 are ωe=1885.33 K,xeωe=22.73 K,yeωe=−0.0106 K,Be=4.2908 K,αe=0.0839 K,De=9.64×10−5 K,β=−2·2×10−6 K. The principal constants for DBr81 are ωe=1884.75 K,xeωe=22.72 K,yeωe=−0.0106 K,Be=4.2876 K,αe=0.0838 K,De=9.59×10−5 K,β=−2·2×10−6 K .
