dc.description.abstractThe rotational spectrum of HDCO in the $4^{1}, 5^{1}$ and $6^{1}$ excited vibrational states has been investigated in Lille and Kiel using a sample enriched in D. In Lille the measurements were performed in the millimeter ($160-600$ GHz) region. The spectra in Kiel were recorded using Fourier transform microwave spectrometers in the regions of about $8-18$ GHz and $18-26$ GHz, employing a rectangular waveguide of 12 m length and a circular waveguide of 36 m length, respectively. These results were combined with the $4^{1}, 5^{1}$ and $6^{1}$ infrared energy $levels^{a}$ obtained in a previous analysis of FTS spectra of the $\nu_{4}$ band (CHD bend), $\nu_{5}$ band (CHD rocking) and $\nu_{6}$ band (out of plane bend) recorded in the $10\mu m$ region at Giessen in order to get the best possible Hamiltonian constants. The energy levels calculation of the $4^{1}, 5^{1}$ and $6^{1}$ interacting states accounts for the usual A- and B-type Coriolis resonances in the $5^{1} - 6^{1}$ and $6^{1} - 4^{1}$ off diagonals blocks. On the other hand, in order to reproduce the observed microwave transitions and infrared energy levels, it was necessary to use a $\{J_{x}, J_{z}\}$ non orthorhombic term in the $5^{1}$ and $6^{1}$ v- diagonal blocks of the Hamiltonian matrix. Therefore, HDCO exhibits an example of vibrational induced rotational axis switching.en_US
