The Submilimeter-Wave Rotational Spectrum of Isopropyl Alcohol

Authors: C. QAJAR, S. MUSAEV

Abstract: The submilimeter-wave spectrum of the {\em trans} isopropyl alcohol was studied in the frequency range from 240 to 480 GHz. More than 170 lines were assigned to ground state transition. The identification of the high $J$ transitions was checked by centrifugal distortion analysis. The frequencies of all transitions were least squares fitted to the Watson's Hamiltonian, including two $P^8$ terms. The ground-state rotational constants are (in MHz) A = 8489.0150, B = 8041.9182, C = 4765.2326, which yield an asymmetry parameter $\kappa = 0.75986663$.
