✦ Synopsis

By direct absorption of submillimeter radiation in a planar supersonic jet, we have measured K,= 1 +K,= 2 transitions of the fully deuterated water dimer (Da)* in the region between 350 and 430 GHz Several previously unknown constants have been derived. The A-rotational constant is determined as 120327.492( 32) MHz. The sum or the difference of the largest tunneling splittings for K,,= 1 and K,,= 2 is approximately 2 1 GHz. The tunneling matrix element hZY has been found to be a factor of smaller than in (HaO)*.
