Quadrupole Transitions in CF3Br Investigated by Two-Dimensional Fourier Transform Spectroscopy in the Microwave-Radiofrequency Range

The ro-vibrational analysis of thev4fundamental band of CF3Br from jet-cooled diode laser and FTIR spectra in the 8.3-μm region

“…The overview of the band is presented in Figure 1(a). A small portion of the prominent Q branch is plotted at larger dispersion in Figure 1 The band shape at lower wavenumbers with respect to the origin appears quite irregular due to the presence of hot bands, see Figure 1 (19) cm −1 , for natural CF 3 Br were taken from a study of the anharmonic effects in the IR spectrum of a solution of CF 3 Br in liquid Ar [51]. The x 34 = 0.3 cm −1 constant is from [26].…”

“…Dipole moments, accurate B, D J , D J K and nuclear coupling eQq constants of CF 3 79 Br and CF 3 81 Br in the ground and in the v 3 = 1, v 5 = 1 and v 6 = 1 states were obtained from investigations carried out in the microwave (MW) and the millimetre-wave (mmW) regions [14][15][16][17][18][19]. A detailed analysis of the hyperfine structure of several vibrational states of CF 3 79 Br was undertaken by means of high-resolution laser radiofrequency double-resonance spectroscopy [20].…”

Chirped-pulse fourier transform microwave spectroscopy of the simple chiral compound bromofluoroacetonitrile, CHBrFCN

“…Spectroscopically they are interesting in regards to how they compare with the relatively well studied polyhalomethanes (for a selection of microwave studies on related methane species see Refs. [2][3][4][5][6]). …”
