Abstract
The spectrum of the double internal rotor ethanol $({\nu}_{OH} = 0,1,2\ldots; {\nu}_{CH3} = 0,1,2,\ldots$ of internal rotation) has been studied in the millimeter-wave region. Approximately 200 lines have been assigned to the lowest trans state $({\nu}_{OH}(A) = 0, {\nu} \ CH3(A,E) = 0)$ and a few have been tentatively assigned to the lowest gauche states $({\nu}_{OH}(E+,E.) =0,{\nu}_{CH}(A,E) =0)$. A three-fold internal rotor analysis of the methyl rotation in the trans state will be presented including previous $data^{1}$. Formulation of a complete molecular $Hamiltonian^{2}$ and the selection rules for the ground state $({\nu}_{CH3}={\nu}_{OH}=0)$ will be discussed.
