Atlas of the O-18 Methanol THZ Fourier Spectrum

In this paper, an atlas of the assigned high-resolution Fourier transform spectra in the range 30-133 cm^-l, corresponding far-infrared torsion-rotation band of O-18 methanol in the vibrational ground state, is presented. The estimated accuracy of the lines is ±0004 cm^-l. This will be of great assistance with our assignments of optically-pumped FIR laser emission in CH₃ ¹⁸0H, in providing FIR data for checking the identification of the IR-pump/FIR-laser transition systems through combination loop relations.
