The (2,0,1) ← (0,0,0) rovibrational transitions of D2O in the near infrared region were measured with a resolution of 0.07 cm-1 using photoacoustic laser absorption spectroscopy. We report on the assignment of newly observed transitions and determine new inertial and centrifugal constants of D2O (2,0,1) using the Watson-type A-reduced Hamiltonian for asymmetric tops.
