 Title: ANALYSIS OF THE OH STRETCH OF METHANOL Creators: Lee, R. G.; Hunt, R. H.; Plyler, Earle K.; Dennison, D. M. Issue Date: 1973 Publisher: Ohio State University Abstract: The OH stretch of methanol has been measured from 3430 to $3940 cm^{-1}$. This extension of our previous $work^{1}$ has allowed a more extensive investigation of the spectrum for transitions involving higher torsional levels. By means of combination differences calculated using the normal state parameters of Kwan and $Dennison^{2}$, several transitions have now been identified. A nonlinear least squares fit of these data indicates roughly a $10\%$ increase in the barrier height in the excited state. The identification of additional transitions is expected to permit a more accurate and more complete determination of the molecular parameters in the excited state. $^{1}$ R. H. Hunt, R. G. Lee, E.
