OBSERVATION AND ANALYSIS OF NEW HIGH-J INTER-SPECIES TRANSITIONS IN $CH_{2}DOH$

Author Institution: UNIVERSITY OF AKRON; KNIGHT CHEMICAL LABORATORY, UNIVERSITY OF AKRON; KNIGHT CHEMICAL LABORATORY, CALIFORNIA INSTITUTE OF TECHNOLOGY; JET PROPULSION LABORATORY, UNIVERSITY OF BRITISH COLUMBIA; DEPARTMENT OF PHYSICS, THE OHIO STATE UNIVERSITY; DEPARTMENT OF PHYSICS, THE OHIO STATE UNIVERSITYWe report the observation and assignments of several series of transitions in $CH_{2}DOH$, including a new and intense series of Q-branch c-type transitions between the $e_{1}$ and $o_{1}$ torsional sub-states through high values of the rotational quantum number J. Other transitions assigned are c-type R-branch and P-branch transitions between these two sub-states and a-type lines within the $e_{1}$ and $o_{1}$ sub-states. The assignments were facilitated by initial analysis of the strong Q-branch series, as recorded by the FAst Scan Sub-millimeter Spectroscopy Technique (FASSST). The assigned lines of $CH_{2}DOH$ include the first in the sub-millimeter-wave and the first to possess high J-values. The completeness of the data generated by FASSST and the success of a simple power series analysis suggest that many parts of the spectrum of $CH_{2}DOH$ may be far more tractable than previously believed. The data should be useful in the development of a full Hamiltonian and in the assignment of astronomical emission features
