Electric quadrupole and dipole transitions of the first overtone band of HD by CRDS between 1.45 and 1.33 μm

► First overtone of HD recorded by CRDS near 1.4 μm. ► Eleven electric dipole and nine electric quadrupole transitions accurately measured. ► Most extensive and accurate measurements of a hydrogen vibrational band. ► Derivation of the electric dipole and quadrupole transition moments. ► Excellent agreement with the most advanced theoretical calculations.
