The 1–0, 2–0, 3–0, and 4–0 rotation–vibration bands of HD have been studied using a cooled multiple-traversal absorption cell and a grating spectrometer; intensities were measured for one electric quadrupole and 13 dipole transitions. There is particular interest in these intensities because HD has recently been detected on Jupiter by means of the 4–0 dipole band. Since the four bands were studied with the same gas samples and apparatus, possible errors in the measurement of their relative intensities were minimized. A rather large rotational dependence was found for the 1–0 band dipole transition moment. The present results are compared with theoretical intensity calculations, and it is concluded that there is good agreement for the quadrupole transition, but not for the dipole transitions.
