“…Thus according to computations, the absorption at 1412 cm -1 is due to mode 19a, whereas at 1513 cm -1 it has its origin in mode 19b. These assignments find further support from literature values [20,21,29,30,32,33].…”

The FTIR spectrum of 2, 5-difluorobenzonitrile has been recorded in the region 200-4000 cm -1 (in liquid phase). The laser Raman spectrum in the range of 0-3500 cm -1 (in liquid phase) has also been recorded. The spectra have been analyzed assuming C s point group symmetry for the molecule. A zero-order normal coordinate analysis has been made for the molecule using force constants derived earlier. On the basis of potential energy distributions and eigen vectors unambiguous vibrational assignments have been made for all the fundamentals of the molecule. Thermodynamic functions have also been computed in the temperature range 200-1000 K by utilizing the observed fundamental frequencies assuming rigid-rotor harmonic oscillator approximation.

“…S 0 electronic excitation. The band origin appears at 33 265 ± 2 cm À1 , which is in excellent agreement with that reported on the basis of UV absorption spectroscopy [13]. It is known that the energy of the S 1 S 0 electronic excitation (E 1 ) can be estimated by various theoretical calculations.…”

“…Spectroscopic studies of tri-substituted benzenes [1][2][3][4][5][6] are quite challenging because these molecules may have various isomers whose spectral ranges overlap closely to one another. Some isomers have similar physical but different chemical properties.…”
