Rotational transitions in excited vibrational states of D2O

Rotational transitions of D2O with J < 12 in excited vibrational states (and the ground state) were measured with submegahertz precision in a pulsed discharge supersonic slit expansion of a D2O/NeHe mixture while scanning the range from 1473.69 to 1685.91 GHz using the Berkeley terahertz laser sideband spectrometer. Assignments were made using all available previous IR results, which include the (000), (010), (020), (001), (100), (111), (130), (031), (012), (210), and (121) vibrational states with levels up to 7500 cm(-1).
