Paper Abstract

The methanol spectrum has been the subject of extensive studies in the microwave, far- infrared, and infrared regions of the electromagnetic spectrum for more than 50 years. The complexity of the spectrum, and the very high quality of the current data lead us to present in a single book all the available spectroscopic information in the regions of broadest interest. Our atlas, currently in press, presents a list of approximately 35,000 assigned transitions from the microwave to the mid-infrared region. The line positions are reported with the current achievable accuracy, and approximate peak intensities are given in this work for the first time. Many new assignments of absorption transitions are presented in this atlas for the first time. The optically pumped methanol laser is introduced, and a list of all the 576 currently known optically pumped FIR laser lines with their quantum number assignments, so far as they are known, are included. The energies of almost 7000 levels, calculated by the Rydberg-Rits combination principle, and the Taylor expansion coefficients for the energy levels are presented. The complete plot of the absorption spectrum from 28 to 1258 cm-1 is given.
