Аннотация

We report high resolution (δν̃⩽0.001cm-1) Fourier Transform Infrared (FTIR) spectra of the trifluoromethane (fluoroform) isotopomer 13CHF3 including results from synchrotron based spectroscopy at the Swiss light source (SLS). The analysis is extended to the pure rotational spectra in the Terahertz (far-infrared) range (15–100 cm−1, δν̃FWHM=0.0006cm-1), the ν3 fundamental (ν̃0=695.292cm-1), the associated “hot” band 2ν33 providing information on the level 2ν3 (ν̃0=1389.807cm-1) and the ν4 fundamental (ν̃0=1369.013cm-1) coupled to 2ν3. The results are discussed in relation to the 13C isotope effect on the vibrational quantum dynamics as derived by theory and in relation to fluoroform as a greenhouse gas.
